A new contemporary art gallery, featuring Island artists, has popped up on the busiest block of Edgartown’s Main street, directly across from Edgartown Books.

Tanya Augoustinos has opened her A Gallery in the former location of a women’s boutique that had moved out and left the shop vacant — one of several empty storefronts that lured the longtime Island curator into downtown Edgartown this year.

“There were quite a few spaces open [and] this just fell into place,” said Ms. Augoustinos, who expects to be in the Main street spot through September while property owner Sarah Levine seeks the next tenant.

After showing fine art at earlier editions of A Gallery in Vineyard Haven and West Tisbury and as a guest curator at Featherstone Center for the Arts in Oak Bluffs, Ms. Augoustinos now has her first downtown location with plenty of foot traffic all day long.

It’s also a partnership, Ms. Augoustinos said during a tour of the gallery last week.

“I said I wouldn’t do this again unless I had someone to help me, because I can’t do it alone,” she said, while introducing Chandler Biggs, a West Coast-trained painter who moved to the Vineyard several years ago.

Together, the two have filled the room with works by Island artists, including the late Rez Williams and Richard Lee, Chilmark painters Kara Taylor and Carol Brown Goldberg — who’s also a sculptor — and author-illustrator Kate Feiffer.

In addition to original works such as Mr. Williams’s stalwart fishing boats, colorful abstracts by Wendy Weldon and Leslie Baker, and meditative still lifes by Barbara Kassel, A Gallery also sells prints by Ms. Feiffer and other artists.

“We have all price ranges,” said Ms. Augoustinos, who opened her first gallery more than a decade ago behind the Scottish Bakehouse in Vineyard Haven and has formed strong relationships with a number of prominent and emerging Island artists.

This month, A Gallery is featuring aerial photographs by Justen Ahren and paintings by Whitney Cleary.

Mr. Ahren, an emeritus Martha’s Vineyard poet laureate who plays music as well, has created a series of black and white aerials that transform agricultural fields into abstract puzzles.

Ms. Cleary also summons mystery with her crepuscular landscapes, which radiate the sense of stillness that comes when night is near.

Around these muted palettes, the rest of the gallery explodes with color — from Mr. Lee’s fantasias on glass, Ms. Goldberg’s bright-red desktop bronzes, James Langlois’s portrait of St. Francis Feeding the Pigeons and a host of other eye-catching pieces.

Fiber works by Julia Mitchell and Nancy Shaw-Cramer add texture to the mix.

Ms. Augoustinos and Ms. Biggs, both of whom reside up-Island, said the bustle of downtown Edgartown is a new experience for them.

“I’m enjoying myself. I love talking about art and getting to know all the artists that Tanya has been working with,” Ms. Biggs said. “And it’s really fun to show off the diversity of the people who live here.”

A Gallery is open at 41 Main street, Edgartown, Wednesday through Monday and by appointment on Tuesdays.
