Original Charcoal of Bull Terrier

Fantastic charcoal on paper of a sweet and appropriately muscular terrier mix, very similar to a bull terrier. Signed by Doris Anderson. The detail in the subject is really wonderful. Age unknown. Currently in a simple thin metal, linen backed frame (Zara) that can be displayed either on the wall or on flat surface. Note: if removed from frame, please be careful of paper edges catching. 

Dimensions: 10.5" x 12.5" x .25"
