The Wyoming State Capitol Building in Cheyenne is equipped with six heavy-duty vault doors. These vault doors were manufactured by the Mosler Safe & Lock Company of Cincinnati, Ohio in the 1880-1890s (these were the same outfit that built the stronghold at Fort Knox!).
But unknown to people of today, these vault doors have a treasure hidden in themselves.
A quick glance is enough to confirm a hefty lock and handle, but modern passersby would never notice that the imposing doors were also decorated with dreamy landscapes and intricate stenciling. It was all hidden under several coats of paint.
The masterpieces on the vault doors were restored last May.
