He's doing a sitcom now , just look at imdb.......

No, he doesn't do standup any more.

I have a cast of Seinfeld photo (Jerry, Kramer, George & Elaine) signed by
Jerry Seinfeld and Jason Alexander (George Costanza).

I would love to get Michael Richards (Kramer) to sign it.

I know he got in trouble a few years ago because of some things
he said while on stage when he was doing stand up comedy.

But does he still do stand up comedy ? Is there a list of tour
dates I can look at online ?

Even a list of his upcoming appearances would be great.

Based on a YouTube video I saw, he seems like a great in person
signer. In the video a woman that was with him had to pull him
away from the fans so that he can make his appearance on a TV show
because he was taking a lot of time signing autographs.
