18X36" Wide, which is $275 plus $35 shipping. That is a hell of a lot for a display board, I figure about half of that would be allright, so I looked at what this company charges for the ordinary display boards... $185 for a 13" x 18". I don't know what other companies charge, but that is too expensive for me
