Field Guide to the Birds
Vintage Field Guide to the Birds - Eastern Land and Water Birds by Roger Tory Peterson.
Published in 1947, this is the 46th printing. I don't know exactly when this copy is from, but I'm guessing the 1970s or 1980s.
Paperback, 230 pages.
Some writing on one of the end pages and a sticker on back cover.
Very good pre-owned condition otherwise.
