It's not Sports Biz per se, but it is memorabilia, which I love to cover.
You've seen the Enron, Bear Stearns and Lehman Brothers memorabilia pop up after their disintegration, but since it was a much smaller shop, Madoff memorabilia is much harder to get. We're pretty sure we got our hands on the two best pieces out there: a holiday greeting card "from your friends at Madoff" and an employee disaster kit.
Here's the greeting card. We bought it off eBay for $12. Are we totally sure it's real? No. But it seems likely. The signatures really do look like they were signed by different people and the fact that there's not a Bernie on here (we've yet to see a Madoff autograph hit eBay) kind of lends credibility to the card.
