My wife, kids, and I have been having a lot of fun coloring the pages of Alice in Wonderland Giant Poster and Coloring Book. The black-and-white illustrations are reproductions of John Tenniel's classic engravings, which are my favorite Alice illustrations, as they are creepy/fun. The book also includes a full color version of each black and white page, along with Lewis Carroll's text. We've been using a cheap watercolor set and it's much better than coloring with crayons, if you ask me.
