Early Photobooth

Smaller than the later standard size.
What decade do you think, folks?
This one is going into the Vintage Enormous Bows Group for sure.
Found in a small antique shop in Niles, CA.
Still trying to decode the writing on the back.
I think the first name is Petras - which is Lithuanian - followed by two other names. There is more writing but very difficult to figure out.
Possibly this is a passport photo?
