I don’t know how to grade books so I’m calling it “very good “, but please inspect the pictures and make your own judgement. Overall pretty good shape. A little wear on the cover, edges, corners, etc. It almost looks like the pages were separating at the spine, but on closer inspection it appears each page is perforated. They all seem attached though. The only mark I could find was the numeral for page 37 is circled although there may be others I missed. Any questions or if you need more pictures just ask.
