A small update, but I've gone though and fixed a few typos, errors, and formatting errors. A few gremlins got by me while I was formatting, and LibreOffice is quite temperamental.
I also decided to remove some of the public domain images, and more importantly: Credit Nick Curtis for the creation of the fonts Parklane NF and Fashion Victim, both of which feature prominently throughout Dieselpunk 1921. I am deeply sorry for missing this credit.
