The effort, going live this week on vickssinussendoff.com, dangles an all-expenses-paid trip to Wimbledon 2007 in London to watch Williams play. The winner and a guest also get to meet and take photos with Williams and receive VIP tickets.
Four first-prize winners get Wilson tennis racquets autographed by Williams, as well as Wilson tennis bags and gear, Nike tennis apparel and DayQuil Sinus and NyQuil Sinus products.
