I picked up these photos in a Pasadena thrift store years ago. There is no information on them except the stamp on the back: Moser & Son, Cin’ti, O.
Aside from the tree (seen below) and what seem to be wreathes in the windows, there is very little sign of decorating.
And there you have it, a spindly Christmas tree, seen through a doorway.
The 1916 Cincinnati directory shows that the Moser studio was at 20 Emery Arcade.
