Monday night’s 40th Anniversary Legacy Gala for the Puppet Showplace Theater looked like a scene from “Alice in Wonderland.” The event, which was hosted at the George H. Wightman Mansion in Brookline, included courtyard performances, music, and, of course, puppets and more puppets. Revelers and performers included Puppet Showplace artistic director Roxanna Myhrum ; Tanglewood Marionettes puppeteer Peter Schaefer ; Ronald Binion , who has worked on “Crank Yankers”; and Mary and Eleanor Churchill, the granddaughters of Puppet Showplace founder Mary Churchill . During the event, the Paul Vincent Davis Award (named for longtime Showplace Theater artist-in-residence Davis) went to John Bell and Trudi Cohen of the performance group Great Small Works. The Creative Leadership Award was given to Susan Linn , director of the Campaign for a Commercial-Free Childhood.
