Here is a pair of nude bookends in a dark finish.  They are not marked but thought they might be either Nuart or Frankart but not sure.  They measure 5 1/4" high and 4" x 4 3/4" across the base.  They have finish wear and what looks like oxidation.  One is missing a little nut on the bottom base. They are in their original condition.  They weigh 4 1/2 lbs.
