I doubt the PDF would be very interesting. There are enough clues in the human-readable parts: it's an invite to a benefit event in New York (filename calls it DBC12) that's scheduled on December 10, 2012, 8pm... Good old-fashioned searching could probably uncover what DBC12 was, although maybe not, it probably wasn't a public event.
