Dear friends, I bought at the auction a pack of old envelopes, with a picture, size 114x161 millimeters (4.5 x 6.3 inches), and I don't know how to use them in Mail Art. Maybe someone wants to receive such an envelope as a gift. In the future, you can make your collage on the reverse side of the envelope, or use it in some other way.
Hi, Katerina! I am very happy. The images on these postal envelopes contain completely disappeared political symbols, which is unusual in its own way. I wish you a peaceful and creative summer!
I keep playing the auction and winning old postal envelopes. If anyone is working with envelopes, using them in their collages, please mail me.
