Today is your last opportunity to visit the Tufts Universities Art Galleries exhibition “Been Here Before,” which features the work of 23 graduating master of fine arts students from the School of The Museum of Fine Arts at Tufts. The show is described as exploring “thoughts of returning or revisiting — whether that is a return home, a return to previous ideas, revisiting constructions before our time, or even revisiting memories.” On exhibit are paintings, sculpture, installation and photography. The exhibition is on view during regular gallery hours, which are 11 a.m. to 5 p.m. Tuesdays through Sundays.
