North American Print Biennial with opening reception from 2 to 5 p.m. Saturday in the Roberts and Raizes galleries at Lesley University’s Lunder Arts Center, 1801 Massachusetts Ave., Porter Square. Free.
More than 1,900 entries arrived for this art show, and juror Judith Brodie, curator of the National Gallery in Washington D.C., accepted 86 for exhibition as the Boston Printmaker North American Print Biennial, at Lesley with a companion student show from Saturday through March 4. The selections cover traditional and innovative media – one print will even grow grass during the five-week exhibition (Eric Avery’s work, above). “Judith Brodie selected works that are bold, broad-minded and intelligent,” says Renee Covalucci, president of The Boston Printmakers association. “The prints on view reveal the issues of today in subtle and overt ways, and will compel a close inspection and reflection to reveal their deep examination of society.” Brodie speaks at 1 p.m. Saturday, with the reception following. Information is here.
