Arabia Moomin mug Evening Swim is illustrated with a fearless Moomin family running on a diving board ready to jump in for a swim. Even Moominmamma is diving head first in to the sea! Looks like she forgot to take her apron off, oh well the summer sun is going to dry it. 

This illustration was taken from Moomin comic strip Desert Island. Evening Swim Moomin collection consists of two spoons, a mug a and a plate as well.
