Frede2025
A stamp set showing gods and deities from scandinavian mythology. This could for example include some of the following:
Gods, such as
  • Odin
  • Thor
  • Loki
  • Freyr and Freye
Other deities and creatures such as
  • The Fenris wolf
  • The midgard serpent
  • The original giant Ymir
  • Odin's eight-legged horse Sleipnir
These are just some examples. I know that the nine realms have already been suggested, so I won't mention them here too.
This stamp set would probably be limited to the scandinavian countries of Denmark, Norway and Sweden.
