All-City photographers Travis Jensen and Brad Evans photo doc book about San Francisco's Tenderloin, aptly christened Tenderloin USA, will have its official launch party on Wednesday night in the 'loin. The bash, featuring good tunes and potent booze, goes down at Ever Gold Gallery (441 O'Farrell).

If you haven't picked up your copy of Tenderloin USA, you can buy one at the festivities. Running $20, all proceeds after printing costs will go to Larkin Street Youth Services, a San Francisco-based charity organization that provides homeless, runaway and at-risk youth between the ages of 12 and 24 with various support services, including emergency shelter, primary medical care, transitional housing, job training and scholarship assistance, amongst other services.

Great party? Great cause? Amazing book? No excuses. See you tomorrow night, folks.
