This peculiar little dude is a paper toy for children – and a great example of vintage advertising. “Le Pere Savon” is built of cubes of soap with “72%” embossed on them, indicating a composition of 72% olive oil – which is typical of the French soap savon de Marseille. I believe he is blowing a bubble out of a pipe.
“Le Pere Savon” was later rebranded “Persavon,” and I don’t find any recent examples of this character in advertising. But you can still build your own personal creepy soap-man using this pattern from Agence Eureka. They’ve helpfully split the full-size original pattern pieces onto A4 size sheets, so you can print them off on a typical home printer. If you make your own, let me know!
