But yikes!
I’m guessing circa early 1960s.
Bonus: It’s the last day of classes for the semester and everybody’s dragging out the Christmas decorations. The Circulation Department is always out of control.
Plus, it just wouldn’t be the holidays in the archives without the traditional “Christmas Tree in a Box”:
It’s some kind of stage; there is a microphone and some stage lighting, and some guy facing the other way on a piano bench. Dunno what that curved wood thing is behind the seated woman is. It looks like a small grand piano but I can’t really make out what is going on with it. The guy on the bench is not within reach of any piano-ish thing over there. And the women are both adorable.
I’m guessing RMC Grand Hall, some kind of literary society spring revue. The dresses look like spring, not winter.
The guy on the bench is facing a piano off to the left.
The curved thing could be a curved-face music stand (or just a barrel).
There is some kind of label on it, but I can’t manipulate the available pixels enough to read it.
There is also what appears to be a curved handle to either a cane or an umbrella.
The curved bit of wood might be the back of a bentwood chair instead of a cane or umbrella.
I think the curved thing is the back end of a trombone. Do I see a spit valve?
