Plans and an isometric view of Butler Hospital for the Insane, Providence, as it was in 1914. Unavailable in high-res on Hathi, as the auto-scanners didn’t unfold and scan the fold-outs. But someone on eBay did, and I rectified their wonky pictures with Photoshop. Possibly of use to RPG and videogame designers who care about the historical authenticity of their game environments.
