A very rare Munch Mammoth, photographed in 1974 at the Texas Hill Country Tour in Marble Falls TX.
This rare motorcycle utilizes a NSU car engine in a custom motorcycle chassis.

I wish this was a better quality image, but it was scanned from a slide that was about 30 years old, it was on Ektachrome film, they had a bad run for several years, the chemistry was off and those images discolored and generally didn't hold up very well.
