I'd open that set and sleeve everything as SOON as I got my hands on it!!! I want the B set AND the 1983 set too... someone had all three, sealed available a couple weeks/months ago... of course it was out of my league, but if I had it to spend on cards, I don't think there's a better place to put "$7K"!!!
Ya and I remember seeing them around back in the day....who knew a complete unopened set would fetch so much? And I have seen auto cards from this set too !!
