A great photo to see first thing in the morning. I laughed with delight. I wasn’t even a glint in anyone’s eye in 1936 but I do remember my first pair of roller skates. I also remember my older sister wearing an outfit similar to the one that the girl on the steps is wearing. Great memories, Cindy.
I think she has the right idea, given those bare little legs. I think my knees were always ‘skinned’ at that age.
