I first heard of this art piece by reading Denis Cosgrove's essay on cartography and modern art in the 20th century. The essay is a brilliant piece of writing that expands the study of artistry and mapmaking beyond the early modern period. While the piece can be found at JSTOR, I have linked it here for your viewing pleasure.
