A beautiful vintage map of the New York City sewer system circa 1865. For more, see The Greatest Grid, which tells the fascinating story of how Manhattan got its famous grid, complete with a wealth of rare archival maps.
File this under “A” for “awesome”!
Here’s Zone 1 of the London Underground map made entirely from drinking straws. I particularly like the use of striped straws to simulate the double-stroked DLR and Overground lines from the real map. Clever work from artist Kyle Bean, who has heaps of amazing work on his website.
