Yeah, that's right, we've got a flag.
It's got a phoenix emerging from a crown of fire above a banner that reads "Oro en Paz, Fierro en Guerra" (Gold in Peace, Iron in War). Oh, it also says "SAN FRANCISCO" real big. Right now you can find the flag in the Hall of Justice or at your local flag store.
