We have Horse Ceramic Book Ends NOS Vintage Items in the base of the original box, no cover.  They measure about 3 5/8" in D x 1 3/4" in W x 4 1/2" in H.  They are a shiny black with gold and a touch of white as accent colors.  There is a place for a pen (no pen included) on one side of each.  These are not all that heavy therefore unless weighted down they are more for show.  They are nos.
