[ New York, N. Y. ]: [ Lionel Corporation ] 1956. First Edition. 40 pages (including covers). Staple-bound. Oblong. 11 1/4 x 7 1/2 inches. Original full color printed self wrappers. Minor edge tearing. A well worn catalog with substantial old cello-tape reinforcements to edges of covers and a few page edges. Stamp of Boston Model Railroad Co on front cover.

A nice color catalog with Lionel's offerings at the time. We know of at least a 1954 edition of a Lionel Catalog with this title as well.
