This is an actual PGA Tour-used quiet sign from the Farmers Insurance Open at Torrey Pines. As an ode to Torrey Pines' location on the Pacific Ocean, the Marshals use surfboard style quiet signs during the tournament. This example is autographed by Phil Mickelson. One sign is offered here - the photo shows the front and the back of the sign. 25" x 5 1/2".
