According to the back of this old real photo postcard, this is Joyce Alma Carrier, aged 4 months. I’ve trimmed the picture, so you can’t see that she’s been plunked down in a chair covered with a blanket and forced to pose for a candid. This young lady is definitely, certainly, absolutely not happy.
I found this at a flea market. Got it for $1. Made me laugh.
The postcard is an AZO, with a square at each corner (this is on the back, the place you place the stamp), which puts it in use between 1926 and 1940.
