"He took Favilla brand ukuleles on the Antarctic Expeditions, but did not succeed in getting any of them flown over the South Pole. A signed instrument was given to the Favilla Company for their museum" -
from Wikipedia.
What a guy, I'll bet he was the life of the party. Interested to know what happened to the Favilla signed uke.
I wouldn't go for a facsimile Martin, but if someone in a dark alley offered me the original.... (I'd return it, of course!!)
