Almost all of them have a logo on the back, some are quite ornate. One has a picture of a house with the word "Melander" above it, that is the name of the studio. One has a poem on the back of it identifying the subject, it is from Boston. The poem reads" Remember me when this you see and always bear in mind that Hilda is my given name and Andersen comes behind". It is a portrait of a woman.
