Group of Seven #518 Lismer 6c Isles of Fire, Misperforation variety on cover.

#518 6c Dramatic misperf tied on cover with 33c 1999 late but non-philatelic use from Acton to Paris, for a lottery. A single vertical cut to the left of the stamp, presumably by a collector clipping the stamps who realized the variety. The raffle form is still inside the sealed envelope. A rare postal use of a variety.
