This is the Gadabout TM 1050 book that we (curioandco.com) presented at the Comic Con 2011. A time machine user's manual, specifically the Gadabout model manufactured by Coworth-Hooper in 2350 but printed in 1953 (they must've gone back in time for printing, we assume it was cheaper).
The book is an actual user's manual, the only thing that is missing is the time machine. It has a humorous take on time travel in the future the model in Gadabout model is a tipical house hold product. You forgot to buy butter for that special dinner that you are cooking? just jump in the Gadabout and to take care of the little things that slipped your mind. In 2350 mid century design is really popular, as it's visible by the manual. It really was lots of fun to do the research, illustrations and design. The book is 96 pages, of how to, illustrations, and trouble shooting. We even talked to a physicists to make sure that it could actually work, and at the time of publication it gadabout used the contemporary time travel theories. Oh I almost forgot... it's full of hidden jokes and riddles based on time travel books, films, location...
