FaceSaver
From Just Solve the File Format Problem
FaceSaver is a format for saving images in the form of an ASCII text file for distribution. It is unrelated to the Remington FaceSaver pre-shave powder. Images are 8 bits per pixel, stored in hexified manner (which takes twice the bits... or more if it's got extra delimiters like commas and 0x prefixes... finding some actual sample files to see the details of the format is surprisingly difficult these days as online face databases have generally been converted to more modern formats like JPEG or GIF). There are also some header lines.
Pictures of attendees at USENIX conferences were taken in this format starting 1987 and stored in a public database.
