This is what the back side of a liberal looks like...Liberal Arts anyway. This was obviously an attempt to bring an old structure into code compliance by adding a freestanding stairway. I can't ever draw or look at something like this without an early mentor/muse coming to mind, M.C. Escher.
Climbing into a drawing like this challenges the spacial part of my brain. Those neurons are firing and when I finish, that muscle feels stronger. Then I throw up.
