Noted landrunner and postmark artist, Ken Turmel, accumulated over 28,600 miles of cross-country travel in order to acquire all of the special commemorative "pictorial postmarks" on Route 66, that were officially issued by the U.S. Postal Service during the 70th Anniversary of Route 66, from 1995 to 1997.
Many of these postmarks are no longer available. One post office in particular, in Cadiz, CA. has already closed down, and its postmark is now lost in time. It is very possible that more post offices will close their doors in the future.
This was the historic importance of capturing all of the Route 66 postmarks onto one piece of art, during the last years of the 1900's.
