1940 Guernsey Bisect, Late Usage

Interesting batch of four Channel Islands items (three covers & one postcard), each with a George VI 1940 Penny Black Centenary 2d commemorative bisect.

Two of the covers are late usage examples (10th & 17th February 1941); with the last day of recognised usage on the 24th.

One cover has an 11th February 1940 date, the result of human error in the postmark date.

The postcard is dated on the 27th February 1945, over full four years after these bisects were in legal use!
