 confusion 

 if summer host passes flag to next summer host and winter host passes to next winter host, were there always 2 antwerp flags (since 1920)?  

 why was oslo flag introduced? i would assume something to do with 2nd flag needed for summer/winter rotation. 

 why was seoul flag introduced?  i would guess (could be dangerous!) that antwerp flag had become too fragile?
