Maud Humphrey, mother of Humphrey Bogart, is well known in certain circles for her Watercolors and prints, many of which are of beautiful children. It is said that her drawing of the famous Gerber Baby was actually her son Humphrey. I don’t know if this is true. I have four Maud Humphrey prints, Little Boy Blue, Little Miss Muffet, Little Red Riding Hood, and Little Bo Peep, which my great grandmother received from sending in labels from Arbuckles Coffee. The prints are approximately 11 inches by 14 inches. My grandfather recalled that these prints were hanging on the wall when he was a boy, which would make the prints about 90 years old. Does anyone have knowledge of these prints, and how to get them authenticated? Thanks for your suggestions.
