In 1989 Blehm published his first PENMEN poster titled, "FIND THE TWO IDENTICAL PENMEN". The 20 x 30 inch poster was covered with 1,039 Penman characters with only two alike.
By the end of 1989 PENMEN posters were selling through a national poster chain, Prints Plus and art distributor, Image Conscious, Inc. From there came Canadian distributor, Imaginous Canada, and Bruce McGaw Graphics in New York. A collection of similar posters would follow throughout the early 1990's leading to a book deal and syndicated comic strip.
