Hi Ron, Business cards came in two precut sized, normal and larger. I cannot remember the sizes or names but I printed hundreds of thousands of them back when. I think the "association" was a one of invention. The Strobocon was a twelve window clockwork monster that likely weighed 40 pounds and was quite accurate because it used Neon lights which flicker with the 60 cycle current. No stretch of course, they didn't know about such when you were born but by the time you were 15 or so they began to get an inkling of it. The rotating wheels has the ability to display maybe 6 partials. Newton
