1d Edward VII De La Rue impossibly Perforated 28 x 14.
The stamp has been doubly perforated, resulting in an impossible stamp with extra wide perforations vertically which can only seen in the sheet margin, however horizontally the stamp perforations measure an impossible 28.
In 50 plus years studying the stamps of Edward VII I have never seen anything like this before.
This stamp is very special and is one of only three examples known.
Unmounted mint
