Anton Orlov said he purchased the 1901 Bellini Jumelle camera and discovered while cleaning the piece that developed images inside the camera appeared to show scenes from World War I, including pictures of war-torn France and a group of uniformed men holding an object that appears to be a bomb, KSWB-TV, San Diego, reported Thursday.
"It was incredible to me that developed images were in the camera," Orlov said.
He said the glass plates must have been inside the camera for nearly 100 years.
Orlov said he will show the images when he takes his Photo Palace Bus to Portland, Ore.
The bus contains a mobile dark room and studio for his photography.
"You should honor history," Orlov said. "Honor the vision of artists and just be careful with your old stuff."
