Description
This is a replica of the punch cards used in the 1890 U.S. Census of population. Like them it is blank with the bottom left corner cut off. Those punching the cards used a pantograph punch which had room for twelve rows of twenty columns of holes. The significance of these holes is indicated on a flat sheet attached at the front of the card punch (see MA.312896). This is one of a batch of cards furnished by IBM.
