For more than 50 years, Terry Seaman of Seattle, Wash., has been producing whatever has come into his head.

The longtime artist and creator will show off what he has been working on for the last half-century on May 1, when Studio 53 reopens with more than 120 pieces of Seaman's art, filling three floors.

The work will range from when Seaman, an owner of Studio 53, was a student to several pieces from 2013.

He said having an art studio afforded him an opportunity to showcase his work.

“You can see the (evolution) as I got older,” he said. “I really wanted to have a retrospective show that shows how my work has evolved.”

That work includes a painting of the footbridge he completed in 1963 when he was a sophomore in high school.

From there, Seaman said his work has morphed and changed while his non-representative style has not.

The canvasses range from 9-by-12 inches to 6-by-12 feet. Some things change drastically, some things stay the same, and some things just need time, Seaman said.

“I started drawing equations in the late 1970s; I would just draw equations, but I stopped doing them in 1983,” he said. “In 2003,  I started thinking about (the equations) and it came to me; 'That's what I should do.'”

Although he dabbles in different styles, Seaman said most of his work falls under the non-representative banner, meaning that it comes from his head and not a still life. When he does paint a still life, he said he likes to choose innate objects like a whittled-down salt block or a cast on a cat's leg to keep people guessing.

“I don't like working with something people will recognize,” he said. “I usually just work right from my head.”
