A weekend art show at the nonprofit Galaxy Gallery in Oak Bluffs has raised more than $17,000 for humanitarian aid in Ukraine.

The two-day benefit opened Saturday with a line of more than a dozen eager customers at the door, gallery owner Holly Alaimo said, adding that shoppers were still dropping by on Monday when the gallery ostensibly is closed.

“People have strolled in and are still buying, [and making] donations,” she told the Gazette by phone from the gallery Monday afternoon.

More than 50 Martha’s Vineyard artists contributed works to the exhibition, with donations beginning at $200 for nearly every piece.

“There were people who came in and they’d been trying for years to collect an artist’s work, but they couldn’t afford it,” Ms. Alaimo said. “The $200 just made it accessible, and they were over-the-moon happy.”

The three exceptions to the $200 minimum were larger works — two Julia Mitchell tapestries and a landscape by Judith Drew Schubert — offered in a silent-auction format that saw bids reaching four figures.

Other Island artists whose work sold Saturday included Leslie Baker, Ruth Kirshmeier, Deborah Colter and Sandy Bernat, among many others.

Ms. Baker, another organizer of the show, said she would be calling more artists Saturday night to fill the wall space left by the day’s sales.

Ms. Alaimo said all of the proceeds from the exhibition, including added donations from customers, are going to Sunflower of Peace, a non-governmental organization in Boston formed to provide medical and humanitarian aid in the war-torn areas of Ukraine.

Galaxy Gallery’s next show opens Saturday with an afternoon reception for a group exhibition by 11 Island photographers.

Meanwhile, another Ukraine-linked exhibition begins Sunday in Edgartown, where the Old Sculpin Gallery opens its season with Colors for Ukraine, a group show with a blue and yellow theme and a portion of proceeds to benefit World Central Kitchen’s food aid in the conflict areas.

An artists’ reception takes place at Old Sculpin Sunday from 5 to 7 p.m.
