The must-have souvenir from Martha’s Vineyard this summer isn’t something you can buy in a store — though you will need a ticket to the Martha’s Vineyard Museum, where visitors are flocking for snapshots and selfies featuring a replica of Bruce, the shark from Jaws.

With expressionless black eyes and a wide, red mouth fringed by multiple rows of jagged teeth, the business end of the movie monster was hand-sculpted for the museum by The Arcana Workshop of Barre, Vt., which specializes in reproducing, well, almost anything the client wants.

Arcana’s recreation of Bruce — Jaws director Steven Spielberg’s name for the mechanical shark in his film — is full-scale but partially rendered, representing about six feet of the original 25-foot monster mounted on a replica of jagged planking from the doomed fishing boat Orca.

Bruce’s mouth, with those bristling teeth, is almost three feet from corner to corner, said Arcana founder Mike Turner, who was commissioned by Martha’s Vineyard Museum after a chance meeting at a trade show last year.

Museum officials first asked if he could make a realistic shark, and then told him more about their plan for celebrating Jaws’ 50th anniversary this summer, Mr. Turner said.

“You had me at ‘shark,’ but now we’re talking about The Shark, like Bruce?” he recalled thinking.

“I was already a yes, and now I’m just: When do we start?” said Mr. Turner, who grew up watching movies by Mr. Spielberg and George Lucas.

“E.T., Raiders of the Lost Ark, Jaws and Jurassic Park and Star Wars films... led me on a path to art school in the ‘80s, because I wanted to make that stuff [with] the interest and talent I had in sculpting, painting and drawing,” he said.

After making his way to Los Angeles, Mr. Turner discovered there was more work available in museums and theme parks than in the movie industry.

“I really got into it,” he said.

In 2015, after moving back to Vermont to work with a firm that supplied theme parks, Mr. Turner started Arcana, which designs and fabricates exhibits for museums and other clients.

To honor the craft workers who built the original Bruce in 1974, Mr. Turner said the Arcana staff used hand-modeling techniques instead of automated equipment to shape the replica from steel, foam and — for the teeth — cast resin.

“This was done like we saw in some of the [Jaws] books and reference photos. The guy has a saw and a big block of foam, and he’s carving it,” he said.

First of all, however, Mr. Turner had to visit the Atlantic White Shark Conservancy Shark Center in Chatham, which has on display a replica of Bruce’s head developed from original Universal Pictures blueprints for the film’s 30th anniversary in 2005.

The Arcana team used photographs and measurements from the Chatham head to design the Martha’s Vineyard Museum replica, installing Bruce in the museum atrium across from the café and the towering 19th-century Fresnel lens from Gay Head Light.

With plenty of room for visitors to circulate, the spot had one major flaw: a wall of windows in exactly the wrong place for photographing the shark.

Museum staffers came up with the solution, Mr. Turner said, covering the windows with a giant still from the film showing the Orca at sea.

“They brought their creativity and ingenuity and problem-solving and came up with the idea,” Mr. Turner said.

Adding a bit more verisimilitude, a yellow-painted barrel from the 1975 production is displayed nearby.

On a recent rainy Tuesday afternoon, a television crew from Boston station WCVB’s long-running Chronicle program was recording a segment in front of Bruce. Other journalists have come from as far away as Greece, museum director Cathy Mayone told the Gazette.

Unlike the original Bruce the shark, which was famously plagued by malfunctions, the museum’s replica has no moving parts to break down. But in an echo of 1974, the moving van taking it to the museum from Vermont last month inexplicably stopped working in Woods Hole.

“We were boarding and the truck wouldn’t start,” Mr. Turner said. “People had to drive around us.”

The Steamship Authority’s portable battery jumper couldn’t restart the engine, so Mr. Turner called for a tow to the nearest mechanic and gave the staff a glimpse of his cargo.

“They were all excited,” he said. “Before I knew it, we were back on the road and we made the last boat.”

The centerpiece of the exhibition Jaws at 50: A Deeper Dive, which runs through Sept. 7, Bruce the shark will remain in the museum’s permanent collection, although Mr. Turner said he is not certain where it will be displayed after the current show ends.

The Martha’s Vineyard Museum is open Tuesday through Sunday from 10 a.m. to 5 p.m. at 151 Lagoon Pond Road in Vineyard Haven: mvmuseum.org.
