Though Kleiber drew, painted and etched wonderful images of the traditional culture of the west, the predominance of his work is landscapes and wildlife, especially as admired through his etchings. In 1931, he received the Silver Medal Award from the California Print Makers Society.  He was a member of the Associated American Artists.  His work is in the collection of the Library of Congress; the Wyoming State Art Museum in Cheyenne, Wyoming; the University of Wyoming in Laramie, Wyoming; the Montana Historical Society in Helena, Montana; The Bradford Brinton Memorial and Museum in Big Horn, Wyoming; and the Buffalo Bill Historical Society in Cody, Wyoming.
