Description

Printer's Devil Hat Sixteen Printer Devils 1933? Allied Printing Trades "Union Label" Council Chicago 103
I believe this is a vintage hat that was back when printer apprentices were called "Printer Devils"
I'm not sure if 1933 is a date or referencing something else.
Hard to find any information on this item and if someone knows more about it or if I'm not correct
please let me know, thanks.
