On the left hand side of this pic you can see 3 of them.
(from the Nicolas Collection
)
These three were certainly ice cream containers. I bought one in Swiss around 1990. Certainly not early 80's, maybe very late 80's.
I do not remember a smurf inside them, just ice cream. Can someone post a pic of these alleged smurfs? Maybe they do ring a bell that way. They have
no hole in the bottom, otherwise the ice cream would leak out. Their hat can be removed in order to eat the ice cream. The mouth (and eyes?) are stickers. I have smurf, papa smurf and indian smurf. I bought one in Swiss as I said; the other two at carboot sales. Which makes me assume they were for sale in Belgium as well.
