America

Dear American friends, how old is this flag? (Without googling 😉)

Only 48 stars / states so first half of 20th century

Exactly. How old it's not is about as far as we can go.

I can assuredly say it is not our flag from 1776 LOL

After Arizona (47th state) and before Alaska/Hawaii. Without Googling, I think that put it between 1917 and 1959, but I'm less certain of the first date

I don't know either🤣 Do you know yours?
