Lot of 2 from 1946. One-sided promo sales sheet is 8.25x10.75”. Features large image of the belt plus detail images noting special features such as “White Plastic That Glows In The Dark/Embossed With Colorful Western Scenes And Brands/Bright Buckle With Secret Compartment.” Additional text reads “Another Builder-Upper For Ralston Cereal Sales The Latest Profit-Building Tom Mix Premium.” Notes availability for 20¢ and one box top, also notes “Offer Starts Feb. 17 On The ½-Hour Tom Mix Show Over Your Local Mutual Network Stations.” Additional Tom Mix image appears at top left along with start date of premium. One tiny .25” corner crease but sheet remains totally bright and clean. Exc. and the only example we’ve seen. Comes with the premium belt although this has been trimmed to half its original size, now 13” in length rather than about 26”. 1” wide with images of cowboys and brands as well as checkerboard design. Metal buckle has embossed image of Mix against checkerboard design, small corner images including crossed guns and “TM” brand. Buckle has slide-out secret compartment. Moderate luster wear but nice highlights remain. Small scattered trace of wear to images but most remain distinct and belt still glows in the dark. Fine. A scarce Mix premium, our last boxed example with instructions sold for over $900.
