X-ray film in the Soviet Union was also used to copy and circulate western music. I think they used retail copies of the records to make their stamper plates, so they probably sounded great! They also wore out fast.
They would cut the X-ray into a crude circle with manicure scissors and use a cigarette to burn a hole. You’d have Elvis on the lungs, Duke Ellington on Aunt Masha’s brain scan—forbidden Western music captured on the interiors of Soviet citizens.
