English: Entitled: Six Strongmen In Traditional Dress, China [1909] W Purdom [RESTORED] Spot corrections, contrast and tonal adjustments; I also more clearly defined the faint mountain line in the background, and increased (doubled) the image size as the original was very small. This of course introduced a lot of jpeg magnification artifact that I then blended with uniform random noise.

William Purdom (1880-1921) was another explorer botanist that surveyed and collected northern Chinese flora along the Yellow River for three years, from 1909-1911; and in Tibet and Gansu, from 1914-1915.
