Know Your Clothes (and Accessories)- The Quizzing Glass

A Quizzing Glass:

"A monocle dangling from a neck-chain- a very fashionable accessory; in the 1820's dandies often had the glass fixed into the head of their canes." - The Dictionary of Fashion History

Used by men and women alike from about the 1790s , it often came attached to a small handle which terminated in a loop, thus allowing it to be strung on a chain or ribbon. It's exactly the kind of thing you can see Sir Percy Blakeney use, when he's not being The Scarlet Pimpernel!
