Lewis Carroll's first iteration of Alice's Adventures in Wonderland was a much shorter work titled Alice's Adventures Under Ground. Although the final product is well known for John Tenniel's memorable illustrations, Carroll himself illustrated his original manuscript.

In fact, many of Tenniel's illustrations were actually based on Carroll's own. Carroll gave the original, handwritten manuscript to Alice Liddell, the girl for whom his heroine was named. It currently resides at the British Library.
