Documentarian and longtime friend of Kurt Vonnegut Bob Weide is selling limited-edition original artwork by the Slaughter House 5 author, Mashable reports.

"Kurt's always made gifts of his art to me," Weide recently told Mashable. "Basically all of the original artwork on our walls is from one Vonnegut or other."

The art sale comes as an extension of Weide's Kickstarter campaign to create Kurt Vonnegut: Unstuck In Time, a documentary about the life of the literary legend.

To make the art available, Weide partnered with Joe Petro, Vonnegut's friend and art collaborator. The two met in 1993 when Petro created a poster for a lecture that Kurt was giving at Midway College in Kentucky. From there, the two struck up a friendship and began using art to bring Vonnegut's ideas to life.

"A lot [of Kurt's art] were doodles that turned into an image," Petro explains. "He'd come up with thoughts and ideas and phrases and quotes, and we'd put them on paper. Some of them were bad jokes that he just loved."
