Mark Grotjahn, an artist best known for his laborious and intricate paintings, is something of a hoarder. Anyone who visits his Los Angeles studio comes back gushing about the strange cardboard masks that litter the space. He started making them 10 years ago, around the time he began the series of abstract paintings that launched his career: his so-called butterfly series, which consist of detailed rays of color bursting from various vanishing points. He would only paint the butterflies in natural light, so he worked in 12-hour bursts, but when the sun went down, he wanted to keep going. He started saving cardboard boxes—including the 12-packs left over from his wedding—and toilet paper rolls, fashioning them into masks with vaguely phallic noses (the toilet paper rolls) and eerily blank, jack-o’-lantern expressions. They are both primal and juvenile; a lot of artists have made masks, Mr. Grotjahn says, but, he hastens to add, so have a lot of kids.
