I got all this stuff at Anime Expo.
I have a lot more autographs than just LiSA's; I didn't pay for them so I didn't post it, but I guess I paid to get in so I'm not cheating here. xD
Signatures include Yuki Kajiura, Kubota Keiko, Otaki Wakana, Egoraptor, Danny Choo (additional autograph for a friend), Oda Kaori and Kaida Yuriko. I also got a signature from Penn & Teller in Vegas, but where in the heck did I leave that picture now...xD
