Best Brass and Marble Swan Bookends!

I picked these Vintage Swan and Marble Bookends up at an estate sale. The brass swans are mounted on marble base. They are in good vintage condition, the marble does have some small scratches and nicks but they are not very noticeable (see pics). The bookends measure 3 inches x 4 inches x 6-3/4" tall. They are heavy and weigh about 3-1/2 lbs each. The swans did have some best uneven tarnish so I lightly polished both of the swans with a scotch bright pad and the polish job turned out well!
