LB-like I said before, it’s only in recent history (1920 is recent history) that people started having these tznius issues. Tznius is not a modern invention – they used to dress and act MUCH MORE tzniusly than we do today.
If people from earlier years would see how things are done today, they would be horrified! I once heard someone point out that we see that even by Achashverosh and Vashti (who were not exactly models of tznius), the norm was that men and women dined COMPLETELY SEPARATELY! Forget about separate tables – they were in different places!
The idea that we are stricter about tznius today is a complete myth!
And it has already been explained several times why the photoshopping was done, so I don’t need to repeat.
