Markus’s personal work began with a focus on American West Cowboys, which is perhaps his most acclaimed subject to this day. “His timeless photographs explore the rugged yet romantic spirit of the cowboy…Markus reveals an era that is all but forgotten today. In his photography, Markus documents a life style of solitude and difficulty, yet to the viewers, a sense of romance; a hard life of plain food, plain surroundings, horses, and exposure to the elements, and yet a simple life free of inherent stress.”

His monumental book, “‘After Barbed Wire’ is considered to be the truest depiction of life on the range since photographer L.A. Huffman published ‘Before Barbed Wire’ in 1956.”
