I do believe that the man who set this fire is almost certainly the very fishy and strange character sitting to the left of those 8 or 9 sections of radiant steam headers. Old Fishy Freddy Creepwater, you can tell it's'im, accurse beckcause he's wear'n 'es funky orange fedora, green nose and blue gills, and even a short area of less-used grey gills below...tuh bust 'im we gotta go in with buttuh an urbs to keep his skerry oal sellf from plannun mo dammidge, and slow fourth. An wheeze awk gotta dew it, cha'all! Ore heez goan eat awl that luvly merrernerrer source whee awl lubb own our Pankiscakes 'n snausages. So go get 'im, boys!
You know, and in keeping with the mentioning of abstract art in the previous comment section, that large blackened concrete square immediately above the taller of the two file cabinets it really does have a rather lovely, non-abstracted, but very clear portrait of a sweet old, all-black little milk cow, her sweet little cow ears extending upward into the next block directly above the first. It's joost luvely, it is...oive nemder her my sweet black Maisie bovine, you GO girl...!
The first thing I thought of was an unpressurized fire hose, as well, which really makes sense, as there appears to be a couple of deeply charred pieces of wood on the steps. Was that fire damage? (A VERY cool pic, BTW.)
Indeed. It's where they plugged in the chair before it shook itself apart and the Janitor had to come and cut off the power cord for the health and safety of everyone who came into that room expecting to use the electric chair after it was broken. Oh, wait...
Speaking as someone who worked in theatres (in the xenon bulb days) and loves these pieces, these are barely worth their value in scrap. There were tens of thousands of these made across the various companies for the theatre circuits and any museum that would want one has easy access to as many as they would like. No question that they are beautiful and the square metal boxes that replaced the arc projectors can't hold a candle (ha ha) to this beauty.
