A steamer trunk comes from the old days of sailing on ships that were called "tramp Steamers'
You were booking onto a ship that was taking cargo from port A to port B, and happened to have a small bit of space for a passenger or 10.
Due to the small space, passengers were allowed only one "steamer trunk".
Essentially what we now call foot lockers.
About four feet by two feet by two feet.
I had one for my first transaltantic passage in 1971.
Disney, in a further attempt to evoke the sailing days of yore, has a pice of furniture, a dresser really, that looks like a steamer trunk standing on its side.
It is about 4 feet high, two feet wide with some drawers/shelves in it.
Thanks for letting me walk down memory lane with this one!
