My first OA purchase was Superman by Curt Swan.
My grandmother passed away when I was 11 (45 years ago) and left a trust fund for her five children. Over the years, two of the kids were bought out at their request and the other three decided to dissolve the trust and distribute it since the balance was small and the costs were high. My dad had passed away by then so his 1/3 passed to his four kids - so I got 1/12 of the trust. or $1500.
Not much in the OA game, but for me it was a sizable, un-budgeted windfall. My wife and I decided that I could splurge with it.
Somehow, I found the Heritage OA auction site and on it were two pieces of art that I really liked - a Sugar and Spike one-page story and my Superman.
Not knowing much about pricing and auctions. I bid on both pieces.
As I watched the auctions, it seemed to me that I'd have no real chance on the Swan, but I might have enough for the S&S. So, though I was really sad to do it, I gave up on the Superman and bet the wad on the S&S piece.
Well, when the auction was over, I saw that I'd lost the S&S piece and was really bummed. I'd bid piddling amounts on a few others and as I scrolled down my lost list something weird happened. The Superman piece was green - HA said I'd won with $15 to spare. I really and truly couldn't believe it until they invoiced me a few days later. I was thrilled.
Be sure to read the description to learn more of the piece's history. It's interesting. (Click on the picture.)
BTW, years later, I got my one page S&Ss story and it has paper dolls, too! Be sure to read the description. I've learned a lot about the piece. (Click on the picture.)
