I cannot see it in Scott,
220 won is a very high value, for the 1970's
There was a set of flags all at 10 won, in 1970.
This maybe one of the many mini "souvenir sheets" that Korea produce,
and a cut from there.
What usage at 220 w is a mystery.
Here is
another at 220 won, no information.
We may have to go to Michel.
