Sweet!!! What type of envelope should I send it in???

Agreed, Mythbusters is awesome!!! {thumb2}

Sorry if this is the wrong forum to post this on but hopefully someone can answer my question for me....I'm a big Mythbusters fan, I have Adam and Jamies autographs but I'd like to get the three other main Mytbusters, Tory, Grant and Kari. I have the address (I found this site doing a google search)...
