Just a fun one. I am not great with dog species, but I think this is a Rottweiler, and I would guess a portrait of the specific Rottweiler who took second place in the 1973 National Capital "Open Dog" Competition. It appears to be hand-painted porcelain, glued I believe to the wooden plaque, and I think would make a pretty nice addition to a wall of dog portraits (or second place prizes!)
7 1/8" x 5" x 7/8" and in great vintage condition. Signed on the reverse by Merle!
