Here is the invitation to an 80th birthday party for David Dinkins at Gracie Mansion, hosted by Michael Bloomberg.
Expect some revelry about the good old days (circa 1990 to 1993), jokes about the political longevity of people who work in City Hall and possibly a humorous anecdote about Rudy Giuliani.
No birthday gifts, though. Tokens of affection (money!) can be donated directly to the Gracie Mansion Conservancy, according to the invite.
