I read that he signs sometimes, and if you send a photo of him as his Pee Wee character he will sign it Pee Wee... not Paul Reubens..

I don't think I was / am being impolite, what threw me off is that the envelope I sent addressed to me and stamped. Had to be a certain size. Now why would it have to be that certain size (minimum size 8.5" x 4"). if I had just sent a trading card or something small? I assumed. That I they may have had a Comicon type photo. Around that size and that's why I had to search around to find a envelope that size to send.

You are asking someone for a favor (an autograph.) It's only polite that you send them something to sign - a photo, index card, whatever. Not all celebrities have photos of themselves to send out, regardless of whether or not you enclosed a SASE for them to send it back in.

I sent him a hand written letter plus a nice glossy photo of pee wee herman character last year around march 2015 and still havent recieved anything i heard he doesnt really sign TTM autographs. is this true? anyone want to confirm? one person on here recieved one but it was a sec. not authentic. so I dont know..i'm still waiting.

you should send a photo to get signed

I sent a letter asking for a autograph 3+ months ago. And now just read I needed to send a photo... So does that mean a photo for him to sign? Because I made sure I had an big, addressed and stamped envelope for the picture. Does this mean I won't get it? I'm confused.
