Old Labor Posters With No Date

[ossean]

I was helping a elderly woman in her 90 clean her older sister apartment who was 98 when you passed on. She use to be a real estate agent in the 60's and 70's . Her sister gave me a can of posters that was just sitting in the closet in a poster can no telling how long. The paper is very old like parched

I wouldn't really have a clue but they remind me of the posters that were in my school classrooms back in the mid to late 60's. Could be earlier though.
