Bark 4 The Art of Rock

Longtime Bay Area rock aficionado and promoter Richard Garwacki gathered a notable collection of posters while managing the historic Fillmore and Warfield Theatre in the 1980s and 1990s for BGP.

Now this collection — stored and unopened for over 25 years — goes on sale May 17 at a special pop-up event in Calistoga, with proceeds benefiting dog-related nonprofits in Napa County.
