The catalog is printed on 8" x 10.5" glossy paper with heavy stock cover. The Ainsworth logo and border around each page is printed in metallic gold, as are various metal parts of the balance on the front cover. The 6 5/8" x 10" price list was inserted inside the front cover when the catalog was received.
