So I just discovered recently about the Easter egg where inside the cockpit of the Tantive IV they placed a small Star Wars poster and a Playboy pinup. Here’s a pic (using a slightly blurred version for obvious reasons).

However while I can’t speak for the pinup since I don’t even know which one it is a closer examination shows that the movie poster is actually the 1984 VHS which obviously couldnt have existed yet at the time the movie was made.

Note how you can just spot out the red triangle with Hi-Fi on it??
