mfl­ogo-font – Meta­font logo font

Th­ese fonts were cre­ated in Meta­font by Knuth, for his own pub­li­ca­tions. At some stage, the let­ters ‘P’ and ‘S’ were added, so that the Meta­Post logo could also be ex­pressed.
The fonts were orig­i­nally is­sued (of course) as Meta­font source; they have since been au­to­traced and reis­sued in Adobe Type 1 for­mat by Taco Hoek­wa­ter.
