I'm using vintage pictures of cards from the early 1900's which are in the public domain. I'm wondering if their names are also safe to use? Thank you!
There are a lot of different exceptions and it depends on when the author died, if they ever registered for protection and how long the works have been in the public domain or when they were put in the public domain
You are copying a card so normally that would be fine; however I'm not a copywrite /image specialist and you should contact one of them for a definitive answer.
