MAILING AND ADVERTISING CARDQ To all whom it may concern:

Be it known that I, WALTER Enxnsr C01.- WELL, a subiect of the King of Great Britain, residing in the town of Oakville, in the county of Halton, in the Province of Ontario, Canada, have invented certain new and useful Improvements in Mailing and Advertising Cards, of which the following is-a specification.

My invention relates to improvements in mailing and advertisingcards, and the object of my invention is to provide a card or device preferably in the form of a folded card or folder which is designed to be unfolded and so used that the stereographs thereon may be stereoscopically viewed, by direct. vision.

With my invention may be combined, if desired, a postcard feature so that the same may be sent through the mails with correspondence thereon; or else my invention may be constructed to be used solely as an advertising card or folder designedto be distributed either through the mails or otherwise.

N o matter how excellent the ordinary picture mailing-card may be, it is im ossible to obtain a stereoscopic effect of t is picture thereon. It is well known that pictures stereoscopically viewed are much more interesting than those not capable of being stereoscopically viewed.

My invention is a broad one, and the claims forming part of this specification cover every and all species thereof. I have shown all the species herein disclosed in order to show that my invention is not a nar- Figure 1,-is a perspective view of .one form of my device opened out ready for use. Fig. 2, is a side edge viewof the form of my device shown in Fig. 1, partly folded. Fig. 3, is a side edge view of an alternative form of my device, partly opened.

The form of my invention shown in Fig. 1.

Specification of Letters Patent.

Application filed September 7, 1907. Serial No; 391,822.

Patented Dec. 15, 1908.

consists of the two cards or body-portions A and B suitably secured together, as by sewing or gumming from. the flaps or wings E and E '(which are seciifed to or formed integrally with the cardsjAiand B) to about the fold D which is indicated by a dotted line. The folding portions F and G of the cards or body portions A and B, from the fold D to the ends H, are not secured together, so that when the flaps E and E are folded inward as shown in Fig. 2, the folding portions F and G may be folded outward and over the said flaps or wings.

C are the stereographs which ma be printed directly on the wings or flaps suitable pieces of materia flags or Wings.

y means of the holes a (or any'other suitable means of construction) formed in the ends H of the portions F and G, and a suitable fastener b passed therethrough, the card or folder is ready to be circulated. As shown in Fig. 7, the inner side of the portion G ma be provided with a space or area for an a dress and correspondence, and for the postage-stam If desired, the inner and outer sides oft e portion F (which sides are notshown), may be used for correspondence also. Upon referring to Fig. 2'it will'be seen that the portions F and G extend beyond the flaps or wings E and E; as a result-of thiseonstruction, when the card or holder-is squeezed longitudinally it will balloon. or open out so that all free spaces suitable for correspondence will be exposed for postal inspection. Various s ecies of my invention may be pro- ,vided wit this feature, if desired. In the form shown in- Figs. 3 and 4, I dispense with the card A and its folded portion F, thus considerably cheapening construction. The

wing E in Figs. 3 and 4, may be suitabl secured in place, as by gumming. When a l the parts of this form of my invention are folded, .as shown in Fig. 4, they are held in place by any suitable means, such as a spring-clamp I.

In Fig. 5, one card is used, and is folded double thus forming the cards A and B and the folded portions F and G; in this form the cards or body portions A and B are not sej cured together. In this form, the wings or fiapsE and E are in the form of the leaves of a book, several of them being secured together and to the body-portion A and B by a the stitching J. I

and E or else the same ma r be. printed upon pasted to the said 7 In Fig. 6, the folded cover made of the f portions 2 and 3, is provided with the stereogra hs (not shown) on the inner sides of the sai portions; and the extension or division ich corres onds to the cards or body portions A and and their folded portions), normally folds between the said portions.

- In order to stereoscopically view the stereothe proper position;

shown in Fig. 1.

.or body portions A and B, together with their folded portions F and G, and the divisione4, divide the lines of vision of the two 'e es when'the device is in use. -Of course t e folded portions F and G may be omitted; the same enables the card or folder to be more conveniently circulated.

In Fig. 81- show a ortion of my alternative form of card or fo der, wherein the card or body-portion 'B is longitudinally slit for a certain distance, thus forming the flaps E cu'lating folding card comprising a body porand E i The placing or' printing of the stereographs in proper position will be readily unerstood by one skilled in this art.

In this specification, and the claims thereof, I use the terms circulating in the :same sense in which it is used in connection with the distribution of printed matter, such .as newspapers and periodicals.

. What I claim as my invention is:

1. As a new fiItlClG- of manufacture, a cirtion used to divide theflines of vision of one eye IIOIH those of theother eye; two flalps of t e having flexible union with one end saidbody portion and designed to fold against said body ortion when the article is closed,

and a sing e stereograph carried by each of said flaps; each 'of the said flaps extending beyond its associated side of said body portion when the article is opened to co-act with the said body portion so that the said stereographs may be stereoscopically viewed.

2. As a new article of manufacture, a circulating folding card comprising two body portions secured together for a suitable distance and each provided at one end with a folding flap, and a stereograph carried by each of said flaps.

3. As a new article of manufacture, a circulating folding card comprising'two body portions secured together for a suitable dis tance, and'each provided at one end with an outward-folding portion, and each provided at the other end with a folding flap, and a stereograph carried by each of said flaps.

4. As a new article of manufacture, a circulating card comprisinga body portion used to divide the lines of vision of one eye from those of the other eye; two flaps having flexible association with one end of the said body portion, and a single stereograph carried by eachof the said flaps; each of the said flaps extending beyond its associated side of the said body portion when opened out to co-act with the said body portion so that the said stereographs may be stereoscopically viewed.

Intestimony whereof I havesigned my name to this specification, in the presence of two subscribing witnesses.
