This appears to be an original paste up of a wanted poster prepared by the Revelare International Secret Service. This agency was formed in 1914 and operated by Luke S. May and J. Clark Sellers. While there were many private detective agencies during this era, what set them apart was the emphasis on scientific crime analysis, which was in its infancy in the United States at that time. While their work was based largely in the northwest, they moved operations to Pocatello, Idaho the following year. In 1919, they again re-located, this time to Seattle.
