Is this a young maid or an old hag

watch the picture

Who drew this picture? A similar chess board art was drawn by a Swiss artist.

This picture hung in my parents home.

This is the first illusion line drawing I remember.
I saw it in a book in the 50's.

This was the next, it is a version of a Mobius Strip.
Didn't know that name till the 80's.
