This is an old sweetie wrapper (actually, I suspect it's a picture of a sticker advertising said sweetie) from Finland, circa 1980.
The name of the product is "Lion Pastilles".
The speech bubble says: "How would you like it if I came in your mouth?"
I would love to know whether someone got away with a whopper, or whether our minds have just grown progressively smuttier with each passing decade.
In any case, I just had to share.
We can now return to our scheduled programme...
Thanks to Populaari for letting me pinch this (a delightful blog full of stuff like this - although, inconveniently for most of you, written in Finnish).
