Signed Unpublished California Photographer C. W. J. Johnson “One Man Band”

Rare Unpublished Famous California photographer C. W. J. Johnson taking a photo of himself with his one man band invention and personal signature on the back.
From my research this is an unpublished image of Johnson and his one man band invention. Unlike his published photo of him as an old man this photo shows a young Johnson likely in 1868-1869 in Eureka, California. This is his is earliest known photo showing his incredible invention!
