PITTSBURGH — The mayors of Pittsburgh and San Diego have a photographic wager for the Steelers-Chargers playoff game.

If the Chargers lose, Pittsburgh Mayor Luke Ravenstahl will send San Diego Mayor Jerry Sanders a Steelers cap, jersey and a pair of skis. Sanders must send Ravenstahl a photograph of himself in the gear while holding the skis at the Sea World Penguin Encounter.

If the Steelers lose, Ravenstahl must don Chargers' swim trunks and a jersey and pose with a surfboard by one of the city's three rivers.
