Interesting item! Made to look like a Railroad time table, it’s actually a catalog for Mar Lines (Marx) toy railroad train parts and accessories! About 4 x 9 inches, it folds open to be about 18 x 24 inches. I don’t see a date, I would guess circa 1960, maybe earlier. Packed with info and images! As shown. Tanned but easy to read. Minor to moderate wear with more wear to edges. Stress to folds, some tearing. Minor blemishes.
