In “Before/On/After: William Wegman and California Conceptualism,” on view at the Metropolitan Museum of Art, William Wegman’s work reminds us that a significant faction of conceptual art has its roots in humorous pursuits. Wegman’s work is funny: it acts quickly and feels distinctly Californian and is in line with someone like John Baldessari, who was included in the show. During the video - Wegman’s donation of 174 of his short videos prompted the show - there was audible laughter from viewers. The humor is dry but rewarding and Wegman seems earnest in his pursuit of eliciting joy. In one video, Wegman, in a near deadpan, creates a narrative between a man and woman where the copyright information of a Merriam-Webster Dictionary acts as points of reference for these characters’ lives, resulting in an ridiculous application of copyright law. The exhibition also featured several playful drawings made by Wegman. “Distorted Vase,” is a twist on “Rubin’s vase,” an illusion where two silhouetted profiles facing one another make a vase in their negative space. The drawing has both profiles but they have been shifted up and down, distorting the illusion. The effect is goofy and succinct: the components of the illusion are present but the shift destroys the negative and the illusion is broken.
