BigTown Gallery in Rochester has previously shown the work of master collagist artist Varujan Boghosian; the current exhibit, titled simply “Late Work,” is his fourth solo show at the venue. The richly colored constructions and collages are visual delights, incorporating references to mythology, literature and, if you look closely, a whiff of political protest. The 92-year-old Hanover-based artist marries wit and whimsy with stunningly precise technique. An accompanying exhibition by Erick Hufschmid features 18 photographs taken in Boghosian’s studio in 2010, along with an essay by poet Charles Simic. Pictured: “Bonaparte’s March” by Boghosian.
