Card image is an archaic term for a character string, usually 80 characters in length, that was, or could be, contained on a single punched card. IBM cards were 80 characters in length, UNIVAC cards were 90 characters. A punched card typically held multiple data fields, some numeric, some alphabetic. Many data formats, such as the FITS image file format, still use card images as basic building blocks -- even though punched cards are now mostly obsolete.

“Rome, the city of visible history, where the past of a whole hemisphere seems moving in funeral procession with strange ancestral images and trophies gathered from afar.”
