Product Overview:These are the same Dry Erase Service Boards that we made for Team Mitsubishi Motor Sports America Drivers David Higgins, and Lauchlin O' Sullivan in 2003 and also for Vermont SportsCar in 2004. Use these Boards to keep your team on time in and out of service avoiding costly time penalties. Space is left on the top portion of the board to affix a clock easily purchased at a local radio shack.Info:Size: 18"w x 24"t x 1/4" thick PVC Plastic
