This one is a scream. Is it the title that turns potential vulgarity into guileless, even sweet bawdiness? It’s just a guy expressing and enacting a natural interest, the fun being that they obviously aren’t, but still look like they are. It’s not unusual to find some artistic rigour besides. The frame is superbly, exactly right, even as Wegman moves back and forth and across within it. Make that an artful, knowing scream.
