Approximately 4 by 2.75 inches. These are vintage style documents so no two are alike. We have received a collection of vintage envelopes, postcards and photographs which have been gathered over decades and reproduced. The perfect accessory for adding a honey touch in merchandising, photo frames, memo boards or scrapbooking. Great for decoupage type projects (we've seen this type of ephemera used as a background for something that will be framed, instead of a classic mat).
