Very unusual piece, a wall pocket, possibly intended as a match safe, with ornate back plate and the pocket a wonderfully detailed funny face, sort of like a drama mask. This is a heavy piece, probably brass plated over another metal, although it could be brass or bronze. We know little about this piece except that it is old and wonderful, in very good condition. It measures 7 & 1/8" tall and 3 & 1/4" wide. We have never seen another one like this.
