I dug this drawing out from near the bottom of an overstuffed box filled with old magazines and a few other drawings by young Richard Page Thurton, whose full name I know from a pile of old school penmanship exercises. This was among several having to do with good health and hygiene habits, and I think would also make a pretty great PSA now. Note the completely logical misspelling of impure.
12" x 9", pencil on construction paper. Paper is somewhat brittle but overall good condition, with what looks like an earlier attempt erased at upper left.
