Two wood mold/forms with wrought iron clamps.  I believe these may have been used for forming concrete foundation blocks or the sort.  Not quite sure.  Possible upcyling/repurposing as shadow boxes mounted to the wall or simply sitting on a piece of furniture.  If your creative, you can make them into a pair of side/end tables by giving them legs and the then mounting a piece of glass to the top opening so you can see down through the glass to the floor.  Quite a lot of different creative possibilities.  Price $75/each (minus the 20% discount, every item every day).
