vertical pair with manuscript "2" cancels on large embossed Valentine's envelope to local street address, cover with few trivial tears, very fine and attractive, very few covers with the Honour's "Penny Post" stamp are known with this being the only multiple, this stamp's period of use was about July 1855 to March 1856 which probably dates this cover to February of 1856, a wonderful rarity
