SDC A1004 Punch Cards

SDC A1004 Punch Cards

<< >>
Description
These bright yellow eighty-column punch cards are rounded at the corners except at the upper right corner, which is cut off in a straight line. The cards contain fields in which the date was indicated with two digits for the year, two for the month and two for the day of the month. A mark in the bottom left corner reads: SDC A1004. According to the donor, they were from a firm of dry cleaners that used tabulating equipment in the 1960s (and perhaps the 1950s) for record keeping.
