This touching, rare, Victoria-era, British cover was mailed out of Leith, Scotland, to Chiswick, Middlesex, via London, by a Rear Admiral Robert Smart, Commander-in-chief of the Channel Squadron, on June 23, 1861! The addressee was his beloved wife, Mrs. Robert Smart! There are some affectionate, last words written to her inside the envelope! Rear Admiral Robert Smart's signature is beneath them!
To continue, as for the rust red, 1-Pence, QV GB issue, outside of the short perfs at its top, left side(caused by a small portion of the stamp's top being torn off), it's in pretty good condition. The rectangular, bar numeral duplex, "221," from the Leith P.O. is superb! The red, transit cancel(on reverse) from the London P.O., is fine, too, but a bit smudged. The embossed seal of the, "Admiral's Office: Channel Squadron," on the back, is awesome!!
Lastly, as for the condition of the envelope, it's relatively good for something over 162 years old. It is pretty clean, with some stains of unknown origin on either side. There is a medium-sized tear in it above the stamp(not IN the stamp).The back flap is intact, though. There is a minute tear in the bottom, left corner, too. All in all, this cover is a nifty, rare piece of mid 19th Century mail from Rear Admiral Robert Smart, who served his country for more or less 50 years(1820-1869!)! He's buried in Chiswick, too.
