Children + Their Fish .. 3 French Poisson d'Avril Postcards

3 sweet hand tinted postcards of children and their fish.
3 Poisson d'Avril (April Fish) postcards from the early 1900s.
Poisson d'Avril is celebrated on April 1st - the French equivalent of
April Fools' Day when people play jokes on eachother, usually with a fishy theme.

Why fish remains unclear, but it might have started in 1564, when King Charles IX
moved the start of the French New Year from April 1st to January 1st.
People who stubbornly kept celebrating the new year at the beginning of April
were mocked with odd gifts, ..often involving fish...because, maybe,
the 1st April falls during Lent when eating fish was restricted.
