Through Sunday, Wolfgang's Vault is exhibiting Bill Graham's prolific collection of San Francisco rock memorabilia in Backstage Pass: A Sweeping History of Rock 'n' Roll at the historic Old Mint Building, whose doors have been closed to the public since 1994.

The vast hallways and ballrooms have been covered with banners, posters, and photographs, displaying the rich history of the performers, venues, promoters, and artists in San Francisco's music scene. The exhibition also includes the original backstage door to the Winterland Ballroom, which was the place to be back in the day.

Visitors will also get the chance to check out the Old Mint's vaults and counting rooms. Exciting!

All proceeds will benefit the San Francisco Historical Society, who are currently raising $83 million to restore and renovate the building.
