We collect unusual stamps. Stamps that have been printed on material other than paper, such as stamps printed on wood, on gold foil, silver foil, tin foil, stamps printed on plastic, on cork, on fabric, on silk, embroidered stamps, embossed stamps, stamps with material affixed, holograms, 3-D stamps, stamps showing lenticular movement and stamps with holes in them. It is hoped that members of the group will notify all other members when they hear of new issues of unusual stamps and that members will be able to exchange with each other commercial covers from their own country showing usage of these unusual stamps.
