Thanks Dan.
I was going through my old scans, and have a couple from 2006. I know that's when an ebay dealer named Big Ed's had a Plank up for auction, and I was the underbidder on it. I took out a loan at my credit union for $16K to try for the card, only to end up as the underbidder. To this very day, I'm still kicking myself in the gluteous maximus for not going any higher, especially considering how that card has risen in price ever since
Here's another scan I have of yet another 150 series Plank:
