Sometimes, I have absolutely no idea how I end up where I end up on the internet. I go to look up something serious and germane. Before I know it, I have found an envelope addressed by the Duke of Wellington. Amazingly, this is actually for sale, from a fellow who has been collecting autographs since 1961. It's not the kind of thing I yearn to own, but I do find it fascinating to see the Duke's illegible writing, and his very seal.
The poor postman who had to decipher that.
If you have a spare hundred and ninety-five quid, you can find the object here.
