A Different Kind of Credit Card

In the old days, we didn't just punch stuff into our computers. If we wanted to shoot credits, there were a lot of steps involved. 
First, you had to write or type or draw each one onto a sheet of paper. 
Then you had to have a picture taken of it and have it turned into a piece of plastic - or a "gel" - as it was called.
Then you had it mounted on a device that shone light through it from behind and you filmed it.
And this was just for the most basic kind of credits - nothing fancy, as you can see from the picture below.
Ugh, I get exhausted just thinking about it.
