Mainzer's mice - walking to school...someone doesn't want to go
Eugen Hartung also did a smaller series of "dressed dogs," "dressed mice," and "dressed hedgehogs." for his publisher Alfred Mainzer. I've only got 1 from this series. Funny thing, Hartung's cats always seem to have dogs & mice as pets but there are only mice in this card. Detail is incredible....notice that the white mice are 'albino' with red eyes while the brown mice have dark eyes.
Artist: Eugen Hartung (or Hurtong), 1897-1973

From a vintage postcard, I have collected them for years.
