Kate Greenaway was a children’s book illustrator in England in the late 1800’s. She drew lots of little girls in bonnets and flowing dresses.
One button depicts two children sitting on a fence with a sunshade and it is titled “Summer.” It is a pierced white metal button and has been tinted purple. The other one shows four little girls and is of stamped brass. They are both rather small buttons at approx. 1 1/2cm.
