I have 7 sheets of black surface and black core foam board that are 3/16” thick and measure 48” x 96”. I also have 10 sheets of white foamboard that are the same measurements. These can be used for displays, photo and sign mounting where a strong rigid lightweight board is required or desired. These are NOS removed from original packaging. Each board lists for over $100 new, so over $1700. Looking to get $600 OBO.
