Probably the biggest QV cover ever sent

Huge 1876 cover, possibly registered though not marked as such, sent LONDON to MARKET HARBOROUGH. Franked a hefty 1/5 with rare (unique?) combination of SG150 1/- PLATE 12 + 2 x SG47 2d PLATE 15 + SG43 1d PLATE ?. Latter stamp has faults.

Sent to Sir William Capell Brooke, brother of explorer and travel writer Arthur.

Showpiece item. Not seen another like it
