Published by Firefly. The 47 amazing pen and ink illustrations were first published in 1967, but in this edition 2003.
There are two prefaces from Steadman, one written in 1967 and one in 1986. I like the earlier one, explaining his decisions on how to draw the different characters.
You can even buy umbrellas with the pictures on :)
…and the amazon link is: Alice in Wonderland, although I’m rather doubtful about the quoted price of over £700…
