30s(I'm guessing from the big hint on the last page)
Correct! I see now that the date is quite visible in the last one, but without it, there is that airship and the ladies' clothes. Amazing that they already had air-conditioning, isn't it?
I did no see the date!! I had guessed 30s cause of the air ship. Sarah
I think another clue would be the lack of women as in the 1950s you already had more women working, including in industry. Contrary to what most people think, it's after the WWII that so many women started entering the workforce.
