Miss Piggy fanmail/autographed photo?

[MaddyLovesPiggy]

I apologize profusely if this has been asked before (I did try the search function and didn't see it, I might have done it wrong!)

My six year old niece just adores Miss Piggy. She says she's her favourite actress! Every time she sees a limo, she says "I hope Miss Piggy is in there!" I was wondering what the current fan mail address for her is? Or if there is a way to get an autographed Miss Piggy photo? She's not quite old enough to be interested in the voice actor/puppeteer, she just wants one signed by Miss Piggy. I suppose I could just fake one, but that wouldn't be nearly as special. Currently she has a magazine photo of Miss Piggy on her dresser that she looks at when she gets ready in the mornings, I thought a "real" autographed photo of her would be even better! I greatly appreciate any help and I hope I haven't posted in the wrong area. Thank you so much!
