Ma Bell Punch Cards

I got these two punch cards from Doug Jones in Iowa, the world expert on the subject (http://www.cs.uiowa.edu/~jones/cards/) while writing an article on the disappearance of punch cards. They're pretty basic plain vanilla cards, but the small AT&T/Ma Bell logo in the middle does kind of give of that large 1950s monolithic corporation trilateral-commission vibe! (which is why I like them)
