The first application of Hollerith'

The first application of Hollerith's punched cards, the 1890 US census, used blank cards.[14] Following that cards commonly had printing such that the row and column position of a hole could be identified. For some applications printing might have included fields, named and marked by vertical lines, logos, and more.[15] "General purpose" layouts (see, for example, the IBM 5081 below) were also available. Some cards had one upper corner cut so that cards not oriented correctly, or cards with different corner cuts, could be easily identified.
