Up for auction is a fascinating 1956 wholesale catalog from United Hobby Distributors, Inc. This spiral-bound catalog, measuring 9 1/2 x 10 x 1 inches, showcases an impressive array of hobby supplies popular during the mid-20th century, including model airplanes, engines, and craft kits. While the cover exhibits significant yellowing and edge wear, the blue plastic spiral binding remains intact and functional. Interior pages show some yellowing but are generally clean with crisp, legible print. This catalog serves as an excellent historical reference and price guide for collectors of vintage hobbies, making it a valuable addition to your collection!
