Here’s the famous Campbell’s Soup Kids, who were created by Grace Drayton in 1904. These promotional cards seem to have been issued as a set of four, and the perforations seen on the cards would seem to indicate that they were attached to each other in pairs. There are also two versions of the cards, one set with the added text “10 cents a can”. This card was postally used in 1909, probably the year of issue.
I can’t decide if these cards feature Drayton art or not. Some of the kids seem like they are spot on (the girl in the yellow frock particularly) while others seem just a little off. What do you think?
