Ah, now I do remember the thing about the Falcon matte... Does anyone know what that picture was supposed to be? I knew that pic in the book was a matte created for ROTJ, but never heard what pic was SUPPOSED to be there instead...

The reason why it was in there is that it was mistakenly put in the OLD definitive making of ESB book. It was a mistake that was carried over into the new one. I'm not sure what he could replace it with, as there are no mattes of the Falcon used in Echo Base. Maybe any of the other mattes... I'm not sure if the 4th printing has started yet, I've messaged Rinzler a few times on various formats but he remains silent.
