7x7x2.5" tall tin litho with built-in key. Several versions of this toy were produced by Marx starting in 1928. This is the final version. Made in Japan ©1966. Colorful box with nice graphics has minor wear including price sticker residue, few light creases and a bit of missing surface paper. Fine. Toy works and features "Honeymoon Cottage" at center that the train travels through. Other features include working semaphore and crossing gate.
