There have been postage stamps in the world since 1840, and commemorative postage stamps with "pretty pictures" on non-postage or state related themes since 1871.
Tracking the appearance of hamsters on stamps is another way to assess their cultural significance through time. It is notable that to begin with, European hamsters appear on stamps as valuable fur-bearing animals. Later, they are totally replaced by Syrian hamsters in the role of pets whilst Dwarf hamsters also make a first pet appearance. By the late 1990s the European hamster has become a WWF flagship species rather than a commodity. This fairly closely mirrors the fame of these species in other situations too.
