Upper Deck will host an autograph signing event with Chargers linebacker Shawn Merriman at its corporate headquarters on Saturday, Sept. 29. Fans who wish to attend must pre-register at www.upperdeck.com/ merriman or by calling (800) 551-8220. Merriman will personalize 2007 San Diego Chargers mini-helmets ($150), deluxe replica helmets ($200), NFL white- panel footballs ($170) and NFL authentic footballs ($220). Fans can also bring in their own items to have signed and personalize for $125. It’s the first time Upper Deck has hosted a public signing event. “This event really gives us a chance to test a new program where we bring first-rate players to the collecting audience in different cities and regions, and Merriman is the perfect star to get things rolling in San Diego,” said Tim Muret, Upper Deck Authenticated vice president. Food, football-themed games and music provided by a local radio station will be available to entertain the fans who attend.
