I think you're right, Roger and that was a very good point about the calling card. Some of the best witness accounts come from those that were seated very close to the box door. One witness account stated the man heard "There's Booth" indicating there was some excitement about seeing the famous actor shortly before the deed.
Could Parker or Forbes not been at the post if Booth made an earlier visit? Who knows. I think we'll have to put this in the forever unknown category with did Booth break his leg on the stage or when his horse rolled.
