I didn’t think Norway had any Olympic stamps, except for Lillehammer, but apparently we do:
And they’re quite nice! I assume the last ones were drawn by children?
It didn’t specifically say, but I assume so. Their names were just posted like any other artist’s, I think.
For those who might be interested, the original Lillehammer 94 stamps are now on sale on a commemorative envelope, with a special cancellation only available on this envelope.
