This all-digital representation of the Mona Lisa was created in 1964 using a Control Data 3200 computer. It took some 14 hours to print on a diazo printing machine and was a popular wall hanging in computer centers, as were portraits of Snoopy, and somewhat more revealing portraits of women in the male-dominated world of 1960s computing. A photocopy of the fact sheet (X1642.99B) appears in the acquisition file.
