In 1988 a gentleman named Paul Middlewick was looking at the (so wonderful) London Underground map when he saw something new and different hidden in the routes. It was an elephant. Since then, he has discovered many other animals from all branches of the animal kingdom hiding in that iconic subway map. He has made a series of clever drawings showing them and is selling them in a book and on T-shirts on his web site Animals On The Underground. I really like the idea of this kind of “hidden art” lurking everywhere around us. You can see a few more below, or click over to his site to see the whole collection.
