The 1968 50th. anniversery Boy Scout and Mexico Olympics stamps were issued on the same day, November 1. I have first day covers of both with the correct cancellation but I also have one of the Scout FDC using the wrong cancellation, that of the Mexico Olympics. My question is has this been seen or recorded anywhere before. Is it a common error or did I stumble onto something special?

The two special cancellations
