Nice government photo of large open pit Johnson asbestos mine. The Johnson mine opened in 1878 as an open pit mine.
The King, Beaver, Bennett-Martin and Johnson mines all mined the same asbestos vein in Thetford Mines. During the 20th century, Thetford Mines was one of the world’s largest asbestos mining and production centres.
Comes from the estate of a French collector who died in 1947.
Paper is a bit 'warped'.
