Large Pepsi Non Skid Glass Trivet - 16.75" Diameter.  I have never seen this item before and research didn't turn up anything either.  This round piece of glass has the Pepsi logo in a non skid form.  The glass is pretty heavy duty.  Be sure to check out my pictures for complete description.  Please contact me with questions, and be sure to check out my other items as I will combine shipments to save you money on shipping.  Thank you for looking.
