Harbor Square Gallery, 374 Main St., will mount an unprecedented solo exhibition by Maine master Harold Garde of Belfast. For the first time, the downtown gallery will fill three stories of its historic bank building with the paintings and prints of just one artist.

The public is invited to the opening reception for “All the Walls” Friday, Aug. 3 from 5 to 8 p.m. during the city’s First Friday art walk. The solo show will run through Sept. 14.

Now in his 90th year, Garde is flourishing and his dynamic art is gaining increasing recognition and support. With decades of museum and gallery exhibitions, two feature films and several publications behind him, Garde continues to explore central forms — including kimonos, chairs and figures — as anchors for the expressionistic language through which he delves into complex realms of human relationship. It also is important to Garde that he has fun in his studio, and he willingly shares his personal quest for truth.

In April, Garde’s massive installation “‘Iconoclass” was unveiled on the facade of the Museum of Florida Art in Deland, along with a prominent museum showing of 39 of his Strappo monoprints. An exhibition of 42 of his most recent large and dynamic paintings are currently on view at the University of Maine, Farmington.

Gallery hours are Tuesdays through Saturdays from 11 a.m. to 5 p.m.; occasional Sundays; and by appointment. For more information, call 594-8700 or (877) 594-8700; or visit harborsquaregallery.com.
