Grosvenor have rare inverted overprint

Grosvenor had a smaller offering of the Jubilee issue than normal, but they did have two items of note. The first was a 1s green and carmine with inverted “GOVT / PARCELS” overprint, still tied to a small piece of parcel label. Only 12 are known to exist. This example was actually a re-offer from a previous sale, but had its estimate reduced to £3800-4000. However, it still went unsold. Also of interest was a dramatically mis-perfed 2 1/2d purple on blue which fetched £260 plus 20% commission against an estimate of £150-200.
