Number of Special Cancels by Year
The above details relate to the CHECKMATE cancels catalogue issued by Hans Ulfströmer/James Sutcliffe, Uppsala April 1975. Until 1979 this catalogue was edited in five volumes in a detailed manner (including cancel images). Subsequently, the cancels were only published in an extremely short list (consecutive numbering, city, issue date, cancel type), ending August 1988.
