I have the Prints of the boy with the yellow hat, and there is another one of a girl with a yellow scarf on her head and gold round earings , and another one of an old man with a white beard a red scarf around his neck and a blue hat, the last one is of an old woman with a red scarf on her head with white hair. They are a set.
They have very nice frames. I had them for at least 20 years, and I always loved them. I don't know what they are worth but I would love to find out.
