![Eiffel Tower blueprints example](https://i0.wp.com/eightface.com/files/images/2009.12.eiffel.blueprints.jpg?w=1200)
The blueprints for the Eiffel Tower in Paris. Apparently, they are reproductions from a book titled The 300 Meter Tower, written by Eiffel himself, and published by Lemercier in 1900. I wasn’t able to find an electronic copy of the book (it’s likely out of copyright), but I did come across another book about the tower published in 1889.
