Scarce Postwar Lionel HO Gauge 1958 Dealer Banner and other Sales Literature. The dealer banner is only the size of two 8 1/2 x 11 pages folded in the center, so it ends up being 8 1/2" x 22". also includes a 1959 sales flyer for dealers and a 1958 8-page dealer catalog with three different dealer displays shown on the back page. These are all in excellent or better condition.
