JOHN GUY PETRUZZI Postgraduate teaching fellow Petruzzi combines traditional watercolor technique with contemporary material in his hyper-realistic renderings on polypropylene plastic sheeting. An admirer of John James Audubon, Petruzzi, too, draws inspiration from nature; his interest in ecosystems and evolution figure prominently. For example, the diptych Prime and Progeny juxtaposes angelfish from the Amazon with variants bred by humans.

CHELSEA MAIDA It’s her final year in the bachelor of fine arts program, and she’s still as interested in exuberance as she was when she started. After four years of tinkering, Maida will debut the final iteration of her signature sterling-silver gummy bear necklace. To her and, she hopes, others, the silver-cast candy evokes childhood magic. Maida also will offer several photo series, each print in a series specially priced at $100.

JACK RODDY He’s still a student, but the ceramicist has sold almost 600 pieces over the past eight years, including one to Museum of Fine Arts director Malcolm Rogers at last year’s sale. While he’s a whiz at the wheel, Roddy has most recently experimented with life-size ceramic skateboards (for decoration only). At this year’s sale, look for his trademark colorful crackled raku wares.

NIKKI ROSATO Through her lacy hand-cut maps, master’s candidate Rosato explores how people’s identities are intertwined with places. Her works are portraits of her subjects’ personal histories, the lines of the roadways as unique as fingerprints. Rosato uses an X-AC TO knife to cut away the spaces between roads, working for up to a month on the larger versions.
