California Historical Society

Established in 1871, the California Historical Society is a non-profit organization “with a mission to inspire and empower people to make California’s richly diverse past a meaningful part of their contemporary lives.” A new logo designed by Palo Alto, CA-based Randle Design was introduced in February. Anybody know what the shapes in the icon mean? Loaves of sourdough bread? Thanks to Pierre Granier for the tip.
