You saved your vacuum tubes and you still speak fluent FORTRAN. All you need now is this collection of two thousand 1960s-era punchcards from the computer sciences whizzes over at International Business Machines. There's gotta be enough data here to start up a game of PONG.
For 21st-century collectors with a taste for retro tech, there is no better stationery, memo pad, letterhead, thank-you note, wedding invitation (check with the bride) or business card material than these historic relics. Intending to put them to multiple use? Fear not: they come in three colours.
