The 'Snow White and the Seven Dwarfs Treasure Chest' dates from 1938 and was designed to be used as a children's toy box. It's constructed from corrugated cardboard with a wood frame and a metal latch and side handles. The lid, front, and two sides are illustrated with a nighttime "buried treasure" motif. The box was produced by Odora Company, Inc., manufacturers of several Disney toy chests. Measures 27" x 13" and is 15" tall.
It's just cardboard, yet the box is still rather smart looking.
The usual "©1938 W.D. ENT." imprint can be found stamped in four different locations on the box--the two ends, another on the top, and one more in the lower front corner.

The box is listed in The Collector's Encyclopedia of Disneyana by Michael Stern and David Longest, p.148 (Collector Books, 1992). Also in the 1974 book, Disneyana, by Munsey, p.311.
