Twenty-three of them, to be exact, all printed on metal, which makes them "gritty."
"Because that's what I saw when I was looking through my viewfinder to the prison," Eberhard said.
"The Arts From The Ashes: An Exhibition of The Old Joliet Burnt District Artists" is on display at the museum through September.
Eberhard's photographic exhibit, "Behind the Prison Walls," will be available for viewing through May at Gallery Seven, which is housed inside the Gaylord Building in Lockport.
An artist reception will be held at the gallery from 6 to 8 p.m. May 4.
Eberhard said she became inspired to create an exhibit last fall after taking one of the prison tours. The museum offers several on its website, including a historical tour, a guard tour and a photography tour.
"Many people don't know what it looks like on the inside," Eberhard said. "While the idea of prison life is foreign to most of us, it's also interesting to learn what it was like there."
