Early 1900s vintage tole metal 'deed box' in minature, measures just 3" x 1 3/4" x 1 3/4" overall. It's a printed design, not hand painted, marked Made in Czechoslovakia. It's clean without rusting, does have some finish wear and scratching.
This has a lock but we have no key - I think probably any small simple key like a luggage key or a diary key would work here.
