Here are two older payroll table cards for use with a Comptometer adding-calculating machine. Cards are titled Pay Roll Table and say Decimal Equivalents of Days and Eight Fractions of Days for 24-31 Day Months, also Minutes Expressed in Decimal Equivalents of an Hour. They were evidently used to calculate pay somehow. One is copyright 1925 and the other is undated. One is for a 17-23 Day Month and the other is for a 24-31 Day Month. They are 12.5” x about 8” and printed on heavy card stock. Both in good legible condition with some wear, light spotting, and light creasing. Printed by the Comptometer Company of Chicago.
