The Klutz Book of Paper Airplanes / How Do Airplanes Fly?

Both books in good used condition but Klutz book does have a bit of shelf wear. Big Klutz book has 55 pages of instruction/designs and measures 9 3/4”X 12”. One or two of the papers for making planes may be missing but still plenty of them left (see photo). Smaller book comes with pieces to make two styrofoam flyers. New to Poshmark?
