Landes was a region of France were stilt walking was normal.
In this photo a French postman walking on stilts hands a letter to a man on the ground. Stilts were a great way to walk on the rough boggy terrain of the region. It took some skill and practice, but once mastered stilts allowed the user to make huge strides and cover great distances.
This quaint practice died out with the advent of the automobile but was still common in the early 1900s. Learn more about the stilt walkers here.
