Humphrey Bogart with Cigarette, Charmingly Naive Vintage Graphite Drawing

Just a fun one; Humphrey Bogart forever. Rendered in graphite, charmingly naive, signed at lower right. C. 1980s I believe--I found it  (at Brimfield) along with a second portrait by the same person (since sold)  of Tammy Faye Baker!

10 1/8" x 8 1/8" framed, under glass, inexpensive metal frame, as found. Ribbed texture of cardboard backing has resulted in some corresponding light toning, which just seems all of a piece with it.
