When Prince changed his name to a signature glyph in 1993, Warner Brothers issues a 3.5-inch floppy with the symbol as a font so that print publications could use it instead of saying "the artist formerly known as Prince."
In 2014 Anil Dash acquired a copy of the floppy for his collection, and just last week he took it to his friends at Adafruit to extract the data.
Thanks to the good work of Adafruit, the symbol is now available on the Internet Archive.
