This sheet was evidently torn off from a larger piece of paper - the right and bottom edges are straight but the top and left edges are unevenly torn, obliterating most of what might have been a signature in ink in the lower left-hand corner. A pencil note at the base of the sheet is also partially cut off, what remains reads: "[...] hall--the butler was having dealings with a [...] extras-wreck on the th[...] thirty. Letter 7."
