The only "evidence" I have seen of the Captain figure
is this photo which I grabbed off of someone else's
auction at EBAY. It appears to have been taken at a
toyshow, and shows a Captain figure on the lower level
behind the SUBMARINE.
This photo (also grabbed off EBAY)
Does not show the Captain figure as part of the line.
The actual figures that I spotted at F.A.O. Schwarz
did not show the Captain anywhere on the package.
