Artist Paul Pagk in front of part of “Cosmic Sex Poem…Children of the Revolution,” his painting intervention last week at “Exhibition,” a temporary space in a vacant storefront at 211 Elizabeth St. between Prince and Spring Sts. A single, multi-artist, continuous work, “Exhibition” is showing for six months. According to its Web site, the artwork is “an intervention upon interventions, belongs to no one and is not for sale, and can be modified, parasitized and destroyed. The artist is drawn from a hat. The artist works in areas determined by a roll of dice.” Pagk said he couldn’t remove the “Vote Hamas” that a previous artist had painted since it wasn’t in either of two spaces he was allowed to intervene in, so he added an “abstract” yellow symbol across from it. Three days later, another artist intervened. The space is open through August, Wed. to Sun., 12 p.m. to 6 p.m.
