Thanks for the Post and lots of props to GUF. Hopefully we can get some updates as the story unfolds more. With the FBI involved, this will not be a happy ending for someone or someone(s).

The shirt has also attracted the interest of the FBI, which as the Daily News reported last month, has already begun an investigation into business practices at Mastro Auctions, sports memorabilia's largest auction house.
Looks like there is at least one Mr. X between Inselberg to Mastronet as the shirt looks like it went from Jim Reed to Eric Inselberg to Mr. X to Mastronet.

Mastronet's price looks like it went for $11,000. Just curious, does anyone know what Jim Reed sold it to Inselberg for?

Reed said he sold the shirt to Eric Inselberg, a New Jersey dealer/collector, late last year, but he is convinced it is the same item Mastro sold this month. "This thing was in my display room for three years," Reed said. "I know my shirt."

Inselberg told the News he sold the shirt at a Westchester memorabilia show in January. Inselberg claimed he didn't know the buyer and since the buyer paid cash, he had no way to contact him.
