Presa House Gallery’s latest celebrates the “unsung blue-collar individuals” who work behind the scenes as art handlers at Artpace, Blue Star Contemporary, Centro de Artes, the McNay Art Museum, the San Antonio Museum of Art and the Southwest School of Art. Devised in 2002 in an effort to bring their creative talents to the forefront, the group show features mixed-media works, drawings, paintings, woodwork, sculpture, video and performance pieces created by 25 preparators — including Anthony Rundblade, Allison Ward, Keeton Foreman, Shane Heinemeier, Ana Hernandez Burwell, Matt Kubo, Jeremiah Teutsch, Raygun Johns and Ed Saavedra. Following the opening reception, “Our Turn 3: 58” on Center” remains on view by appointment through February 27.
