Lot 50010 – 1841 1d Red pl.1b, 1c and 1d PB-TC block of 10 on

1841 1d Red pl.1b, 1c and 1d PB-TC block of 10 on 1841 (Jul 7) large envelope from York to Sheffield, mixed margins, tied by black MCs, cover slightly soiled and vertical fold affecting two stamps. This is the largest 1d red plate 1 block on cover, one of the largest blocks known (possibly the largest in private hands) and almost certainly unique in showing plate 1b, 1c and 1d. A must have for the specialist line-engraved collector.
