It’s a safe bet that in 1967, when Mari Tepper created a calendar-poster for the “New Merchants and Craftsmen in Haight Ashbury,” she probably wasn’t thinking too hard about posterity. But 50 years later, Tepper has reprinted her 1967 calendar because its dates and days of the week line up perfectly with 2017’s.

We’d like to give you one. A limited number of Tepper’s reprints (shown above) will be available for free—first come, first served—at the 2017 Festival of Rock Posters at the Hall of Flowers in Golden Gate Park. The show takes place on October 28, from 10-6. For the latest updates (the roster of artists and vendors will be announced in September), check out the event page on Facebook.
