I'm so impressed. I certainly wouldn't have got more than two. Anyway, in case you haven't seen the answers compiled by the Brains Trust in the comments box, here they are.
Sorry about the wonky layout, I spent too much time trying to sort it out, failed; and have decided not to spend the way too much time it would presumably take to succeed.
A few unsorted thoughts: Marx is my favourite. At first, it's inconceivable that Marx ever looked like that - but put the pictures side by side, and suddenly old Marx is just young Marx in a Father Christmas costume. Look at his eyes and nose - they haven't aged at all.
All these people lived relatively long lives, and yet, even with the evidence before me, it doesn't really change the way I feel - that the unfamiliar pictures are an interesting curiosity, but that Queen Victoria was basically always an old woman, Chaplin was always a young man, and Cary Grant was always about 45.
Alice Hargreaves, nee Liddell, was still alive in 1934! There will be people alive today who remember her. Crikey.
It's encouraging for those of us who plan to become old men that whilst handsome young men (Chaplin, Grant) turn into handsome old men; plain young men (Darwin) can do the same.
Talking of Darwin as an old man, can it be entirely coincidence that whilst his rather simian brow and deep set eyes make him look more like an ape than most men; his white hair and flowing beard make him look considerably more like God? And if it's not a coincidence, whose joke is it?
And speaking of God liking a joke, let's hope he does, because conversation in the comments somehow lead me to promise the following in return for a completed quiz sheet:
