This framed vintage Paint-by-Number of a Cocker Spaniel was manufactured by Pann Products in 1952. It's from the Paint-a-Number Canvas Kit Series. This PBN has some spotting (look closely at the photos and you'll see it at the top of the painting and the bottom) but it's pretty minor and it still displays well. If you know how, you could probably clean this oil painting so it looks good-as-new.
The frame is original and is the 1.5" oak frame. Unframed, the PBN is 9" x 12" and framed it's 12" x 15."
