Great Britain 1986 17p Royal Wedding of Prince Andrew and Miss Sarah Ferguson (from photo by Gene Nocon) error, SG1334a.
A very fine unmounted mint, with full original gum, imperforate left hand marginal pair.
A very scarce QEII stamp error. Pierron records only 45 mint imperforate pairs in existence. The error was discovered on a sheet in Newcastle-upon-Tyne, which was almost completely imperforate other than the top left corner.
