Last year I did a post about Li'l Abner at my vernacular photography site. I was questioning whether or not I am in possession of an actual photo of Mammy Yokum. Strangely this photo now shows up on the first page of Google's image search for "Mammy Yokum" so I guess this poor woman and her kin will go down as having lived in Dogpatch.
