This listing is for 4 books in this series. The copyright page says copyrighted in 1922. But these dust jackets look like they might be more from the 30s than 1922. The dust jackets are all fragile, but the colors are still great. The pages of the books are all yellowed, and have foxing as you might expect from a book that was 100 years old. I’ve never sold books before, but these came into my hands and I thought I didn’t need them, so I’d List them. If you have any questions, please let me know before you bid. I’m happy to answer anything I can. I just don’t know much about selling books.
