Fun Toilet Facts is a series of diagrams and was contributed to Bureau Stabil’s toilet-themed fanzine “Klolektüre” (toilet read). The entry uses (then newly released) Granville, a modulated sans by Production Type. The crescent moon in Average loudness of toilet flush is a Webdings glyph.
Bureau Stabil published the fanzine to support WiWo e.V.’s “Mpigi & Tiiti School Project”, a local fundraising event. WiWo is a Saarbrücken-based charity group of like-minded friends with diverse projects. Back then, they were supporting an Ugandan elementary school with plans and help for new toilet facilities.
