Philatelic Feud - "Fish with Legs"?

How gorgeous are these contentious Hawaiian Missionary Stamps?

(According to today's NY Times, the London and the American Philatelic Societies are in conflict about whether these 19th c. Hawaiian missionary stamps are forgeries or the genuine article. Apparently they are something of a "missing link" in the stamp world, hence the "fish with legs" comment by a Mr. Sundman.)
