Old master drawing - Study of game attributed to Benjamin Blake

This is a lovely old master drawing which I am attributing to the artist Benjamin Blake 1757-1830, as yo can see the work depicts studies of dead game which is what Blake was famous for and the execution of this is very much in his hand. It is executed in chalk and heightened with white. The work measures 10x8.5 inches - image and comes framed. The condition of the work is generally good considering its age with only a few spots and the mount has evidence of staining but it is an old work which dates circa 1800s.
