Artist Victor Ekpuk says on his website, “The subject matter of my work deals with the human condition explained through themes that are both universal and specific.” For his touring exhibition, “Auto-Graphics,” at the Hood Museum of Art through August 2, the Washington, D.C.-based artist communicates his emotions with graphite on paper. His self-described “stream-of-consciousness style” employs symbols and a secret-code language called nsibidi that’s used in his native Nigeria. From Tuesday through Friday, April 21 to 24, visitors can see Ekpuk in action: He’ll be drawing a mural on the wall of the Hood’s Lathrop Gallery on the Dartmouth College campus. Check the museum website for “performance” times. On Friday, April 24, at 4:30 p.m., Ekpuk will give a talk, followed by a reception. Curator Allyson Purpura will lead a tour on Saturday, April 25, at 11 a.m.
