These are the Blueprints of the two floors of the actual Jail in Crown Point Indiana where the John Dillinger escaped in 1934.... The film Company used the real Jail to film Dillingers escape... The prints were made by the studio in order to renovate the areas in which they would be using to film the scenes they needed...
They were left behind and stored in the attic of the real Crown Point Jail up until I purchased them in 2020...
