Often photographs and real photographic post cards have little or no information to identify the time, person and place. In the case of this photograph the notes on the reverse tell us everything about the location and describe in obsessive detail everything “Ruthie” is wearing even down to the charms on her charm bracelet.
The photograph is numbered (766) and dated at both top and bottom on the reverse which suggests it was filed in a manner to make it easy to locate. You have to ask if this is number 766 then how much more information was attached to the rest of the collection and how big was it?
Now that’s what I call obsessive.
