Query: 19th-century Jewish books and photo-offset reprints

I am looking for ways to tell whether a Jewish book whose title page says it was printed in Eastern Europe in the 1800s was actually printed then or is a later photo-offset reproduction. I posted this query previously and received some helpful answers but was also told that my question was not clear. Here is an expanded version with photos to clarify what I am talking about. https://justinjaronlewis.wordpress.com/category/research/ ("Jewish Book Questions").

Thank you in advance for any advice.
