This is a unique piece featuring a chromolithograph of a bull dog. He has a red collar on and the number 99 is on the image. The bull dog is under an indented two tone matting. When I researched it, it is shown online on several sites as a 19th century tobacco crate label.
He is in a more contemporary frame with glass, a dust cover, and a wire for hanging. It was professionally framed in Somerset, Mass. and is stamped with a number.
Size: The frame measures 17" tall and 9 3/4" wide.
