Uppercase Magazine (completely new to me) is working on a new book about the graphic history of the typewriter. This project promises to be very interesting. Janine Vangool, the architect of this project has put together a small video detailing the hows and whys.
The interesting thing about this book is that it is a completely graphic look at the world of the typewriter. Based on what the video describes a significant part of the book is dedicated to ephemera and advertising. For people who are at the intersection of the typewriter-graphic arts Venn diagram, this promises to be an interesting book.
The project is being funded by Kickstarter and it looks like there are miles to go before the printer, but it is over half-funded. It will be interesting to see how this book turns out. Click on this sentence to be taken to Uppercase's page about the book.
On a final note, Janine is looking for interesting examples of typewriter ephemera. From what I can understand she would like to work with you to scan the material. I know that the Typosphere has more than its fair-share of interesting materials.
