FaceSaver

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... which there aren't in this case, though there are some newlines, but 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.

Identification
One of the header lines begins with " ", and another with " ".

Editors' notes
Many image format lists include something called "Usenix FaceServer" format. Is this another name for FaceSaver, or a transcription error, or a different format? Note that XnView claims to support FaceServer format, but is unable to open FaceSaver files.
