I have seen a lot of these cards on Ebay with two different color signatures, blue and black. Does anyone know if there was a difference in the two colors (print run, etc)? Any comments would be greatly appreciated. This is what the cards look like:

Don't know anything about the ink color, but there are two version to get - the standard (1:24) and the gold (#'d to 25). the gold has an extra card in it - but I've no idea who it is.
