Why 18 Reasons? If you’ve been in the Mission for a while, you may remember the large sign atop a building at the corner of 17th Street and Mission. It simply, and mysteriously stated: 17 Reasons. It was tragically taken down in 2002 and replaced by an ordinary billboard. To mark the change in the gallery’s management and pay tribute to this much-missed icon, we decided to rechristen the space as 18 Reasons. 18 because of 18th Street, and because…well, it never hurts to have one more reason.
