Don’t be fooled by the subject matter, the dolls on display in the art exhibition ‘Journeys Through Light & Dark’ aren’t mere playthings; they’re storytellers. The group show, co-curated by sculptor Sherri Morgan and Sonoma State University psychology professor Geri Olson, features over a hundred dolls, sacred or fanciful, from ancient and modern times. Running through Sept. 25, the show offers a curator tour with Morgan and Olson talking about various pieces, the artists behind them and techniques used to create them on Friday, Aug. 19, at the Petaluma Arts Center, 230 Lakeville St., Petaluma. 7pm. $10. Advance tickets required. 707.762.5600. petalumaartscenter.org.
