I have the following posters in my Grey's Anatomy magazines and I need some help on some questions

1. George and Izzie would they both sign it and send it back or would I lose the poster?
2. Alex and Addison would the both of them sign it and send it back or would I lose it?
3. Cristina and Burke would the both of them sign the poster and would I lose it or get it back autographed?
4. Denny and Izzie would they both sign the poster and would I lose it or get it back autographed?


Denny, Addison and Burke are no longer on the show how can I get there autographs?
