cmokingBarry and Ted,
I was thinking that if there were other red background cards that had a pinkish look to it, that would give some credence to the theory that the Keeler pink card was due to low inkage. In the absence of other red backgrounds and pink background cards (like the Keeler) with the same exact image, that theory seems to have less support.
Also, with the two pink background cards that Ted mentioned, it seems the printers deliberately printed cards with the pink background and it wasn't a low inkage.
