Old computer punch card without holes.

Caption: This is a punch card such as was used to enter w:Fortran programs into the mainframe system at the University of Missouri - Rolla in the late 1970s. The beveled corner on the upper left ensured that all cards were oriented the same way.

[edit] Source

I was showing my old college calculus book to my son and found several of these in the pages – we would take stacks of them from the keypunch room to use as note cards and bookmarks. I scanned the picture and claim no rights to it. Kbh3rd
