“Two Heads are Better than One”is the title of an exceedingly demented collaborative exhibition by Theo A. Rosenblum and Chelsea Seltzer that opened on Valentine’s Day, Feb. 14, 2012, at The Hole. Like pranksters scrawling mustaches on beauties and blackening out their teeth, Rosenblum and Seltzer have run amok, defacing the tawdriest decorative objects they could find with bizarre and malicious painted and sculpted additions.
