A birthday toast to San Francisco’s Legion of Honor Museum as it turns 100! — as would Edward Gorey if he’d stuck around till 2025. You can celebrate both centennials by stopping by for a signed copy of The Theatrical Adventures . . . (and don’t miss the double exhibition on theatrical set design down the hall). Unsigned books also available at the DeYoung. Both museum shops are chock full of choices for holiday gifts and cheer!
