Thank you very very much Kristiina for this wonderful cover from Estonia with 4 WWF stamps!
The stamps picture the European flying squirrel (Pteromys volans) and were issued in 1994. These animals have a membrane that extends between their fore- and hind limbs. Unlike some other species of flying squirrels, Pteromys volans do not have a membrane between their hind limbs and the base of their tail. Their limbs are relatively short and thick and their hind feet are significantly larger than their forefeet. The length of the head and body is 120-228 mm.
