Does it have the King of Hearts on the cover? Frederick J Drake & Company printed a paperback edition starting in 1905 and printed them until the 1930s. How do you know it is a first edition (of the paperback version)? Does the King of Hearts have pips? What colour is the background? It should state the publisher on the title page, does it say Frederick J Drake & Company?
there are too many questions for anyone to really tell you what it would be worth with out seeing it, what kind of condition is the book in?
