These are old! Johnny Carson did a bit with these on one of the Tonight Show episodes. I remember sticking these on cars when I was a kid in Elementary School. In fact, not only that, but I recall printing them on my High School's offset printer as a project in my "Graphic Arts" class.
Wow! Graphic Arts class! One of my best High School memories (I didn't care for Wood Shop). The fellowship we had with both the teacher (who doubled as one of the HS's Football coaches) and the other students could rival some of those in the Military. It was a complex process to bring something from a design concept to the printed page, but the highlight of it was being able to operate the school's AB Dick 360 CD (Chain Delivery) offset printer.
I could run that thing today, if presented with a working one. It was just like riding a bike. It had a rhythm to it when you turned on the Motor Drive. There were kids in the class that used to "dance" to it.
The paper feeder (on the right side of this view) had a vacuum bar with "sucker feet" on it You could turn on the "Vacuum Pump" (independently of the motor drive) and it would create suction in that vacuum bar. When you pulled the lever to begin "feeding" paper, the vacuum bar would lower and the sucker feet would grab one sheet of paper and feed it through. It would go through the blanket and impression cylinders and out the other side where a set of catches on a chain would pull the paper out and drop it on the end tray (on the left). Hence, the term "Chain Delivery" or CD. I got good enough in class to do "Duo tone" pictorial images (2 colors). Didn't make it to "four color separation" (i.e. "color pictures") but it was possible.Good times.
