Charming antique suitcase with travel stickers.

A charmong American antique suitcase with leather corners and straps circa 1930's. There are 10 paper travel stickers = London. New York, Rome, Venice, etc.. Good condition with some light scuffs, wear and losses to the paper stickers. Presently I have not found a key to open it??? Size: 26 x 13 x 8 inches. This is a very nostalgic object of the old days of travel.
