Leopards in England? Yes, by the early 1800s the population of larger towns would almost certainly have seen leopards. The menageries that toured England carried with them all sorts of ferocious felines. These menageries were educational showcases of sorts. The animals did not perform; their mere presence was entertainment enough. People from far and wide flocked to menageries to see if hitherto mythical beasts really existed.
The leopard below is a lovely Sherratt-style figure.
This leopard, on the other hand, is a monster. It is a very modern copy of the real thing. Look at the difference! I returned from vacation to a flood of emails, most of them asking about figures that are blatant repros of just this sort. Buyer beware--or ask me before you commit. Happy hunting!
