Using my recent example of a screening I'm attending with Craig Robinson (Office) and Seth Rogen, I was wondering what people thought in terms of selecting photos to get signed.  As I'm not a dealer/multiple grapher, I usually just take a photo or two at most along with me.  In Seth's case, I'm debating whether to get a solo pic, movie poster from the screening (Craig is also on it), or something with him from Pineapple Express or another one of his bigger films that I could potentially get others on.  Do you have preferences when it comes to choosing what type of photo to bring?
