This cute creature was created in 1941 and was part of a vigilance propaganda campaign in Sweden. The slogan "En svensk tiger" is a pun. Tiger is tiger in Swedish as well, but it can also mean "to keep silent", meaning that a Swede don't blab secrets to strangers.
The designer was Bertil Almqvist and in Sweden he is also well known for a series of children books, mainly written in the late 40's-50's, about a Stoneage family who travels around the world, for example Egypt, USA and Britain. They even travel to the moon and Mars!
