In addition to cool collection of Alice in Wonderland art, this website has a neat background story on the famous tale:
In Carroll's original (1862-1864) manuscript for the story, Alice's Adventures Underground, which he personally illustrated, Alice was not the little blonde girl in a pinafore we have come to know from subsequent illustrations.
Instead, she was originally a winsome, dark haired child, whose likeness had been patterned after ten year old Alice Liddell, the child of a church colleague, for whom the Alice stories had been originally created.
