content: This bright yellow punch card has eighty columns of digits, with the digits from 0 to 9 in each column. It is rounded at the corners except at the upper right corner, which is cut off in a straight line. The card contains 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. According to the donor, the card was from a firm of dry cleaners that used tabulating equipment in the 1960s (and perhaps the 1950s) for record keeping.
