Gutter Pair
The philatelic use of the word gutter is the space left between postage stamps which allows them to be separated or perforated. When stamps are printed on large sheets of paper that will be guillotined into smaller sheets along the gutter it will not exist on the finished sheet of stamps. Gutter Block of 8 (mint condition) depicting the Marriage of HRH Charles, Princes of Wales and Lady Diana Spencer, issued in 1981.
