Good afternoon! Was wondering if anyone could place the era of the cap. I'm yet to find one like it. Any help would be greatly appreciated; it was an estate find. Thank you!
This looks like it, but I don't read Polish so I don't know the era. Śmierć szeregowego w Ustroniu Morskim. Możliwe samobójstwo
The design of that cap is basically timeless, they always looked like that. But the eagle is a "communist", from the period of the communist regime (1944-1989). Of course, it's extremely unlikely it's from 1944 or 1945.
