Obsolete industrial bric-a-brac hanging on the outside wall of an erstwhile cement plant. In line from top to bottom is something that appears to be a broken chute. below that is something that looks like a wall mounted mailbox. Below that is a circular metal plate with eight bolts on the edge and a label in the middle that reads: Confined Space Entry Permit Required. Beside all that is a ladder, on which I would never like to find myself.
