Alexandra, lived a little-known artist Marie, Mizzi WUNSCH (1862-1898).
Wrote good episodes from the life of children.
But the really famous for only one work, the original name "kleines Geheimnis"=little secret.
She has written countless repetitions in different sizes, technology and quality.
This is one of the most popular, classical, works to be copied.
One of the reps actually on Ebee on sale (though not the fact that the original):
