This dates from around 1990, and was produced by a company called Bear, Bear & Bear. They are a UK company with a reputation for witty and wacky toys.
This is really just a pair of socks, but as they say, it is all in the presentation! The socks poke out of the plant pot, looking just like some kind of exotic leaves; the label gives the formal name - Greenus sockus - and it is only when you pull the leaves from the pot that their true sockiness is revealed!
