Each unique artwork consists of mint postage stamps placed on colorful, hand-painted backgrounds of state border outlines. These very large pieces of artworks are then hand-carried to hundreds of post offices throughout the United States, specifically for the purpose of acquiring historically significant postmarks to be placed directly atop the original artwork background. Each postmark is inked in its own city and mile by mile the artwork blossoms into a wonderful collage masterpiece. His methodical procedure of personally delivering each artwork to each and every post office is never compromised.

The "pictorial postmarks" which were placed on the artworks, commemorating specific celebrations along Ken's postmarking routes, have all expired and have been destroyed by the postal service according to regulations. This means that the PostmarkArts become historical documents at the same time as they are being created. These works have been acclaimed to be a first of its kind by over 1000 postmasters and postal officials, including many confirmations from various museums, collectors and professional artists.

Frequently dubbed as "the land runner", Ken has accumulated well over 150,000 miles of travel gathering postmarks and autographs within a 20 state region.
