1940 call it courage

Not much unless you learned how to read in a hebrew school.

The value in such items resides in their relative rarity. Unless someone here who responds is an expert dealer in rare books, i doubt that you're going to get a reliable response. You would have to consult a dealer in rare books, or someone else who is an expert appraiser, and you would likely have to pay a fee, even if the answer proves to be that it is worth nothing.

Abes books can give you an idea. They are on line and deal mostly in oop and rare books and maps. They do handle printer goofs too. Ive seen values all over the place.
An annotated "Book of Kells"would be priceless, but alater edition of "Heart of DArkness" with blockprints upside down would be worth whatever a yard sale could get.
Recent book misprints are not that valuable
