Could it be that he's using a similar concept for the new ones? You know, the new poster seems oddly hanging on the left, like it may continue with another one on the right. Maybe next to Han there are actually other two figures: Luke and Leia.
That poster isn't the movie's poster... it's a teaser poster specifically painted for Disney's D23 Expo. Why do you think it says "December 18" below the title, while credits and company logos are missing?
