Alice In Wonderland
There are over 20 illustrations from Alice In Wonderland by artist Khodozhnik S. Goloshchapov on display in this gallery. I've seen strange interpretations of the Alice tale but these have to be some of the weirdest.
Below is another Alice In Wonderland illustration I found on this page. And as pointed out thanks to Paul Rumsey, this is actually an illustration by Lewis Carroll.
