The Detroit Institute of Arts upcoming exhibit
"Diego Rivera and Frida Kahlo in Detroit," which opens March 1,
will include 8 "cartoons", preparatory drawings for his 27-panel
mural "Detroit Industry". The drawings are 83 years old and were
discovered rolled up in the basement.
See the Detroit Free Press article on the cartoons' restoration:

The murals are magnificent.
