An interesting overprint, considering Australian preference to not overprint
where possible. This one, for Norfolk island, with, an even more interesting surcharge.
This was an emergency overprint as the postal rates had suddenly increased, leaving
Norfolk Island with no current letter rate stamps. See Antarctic,
for similar overprints.
