Ryan, mind showing me when Han wore blue and wielded a lightsaber in the movie then? ;)
That was all I could find on short notice, Ralph did do paintings of the original Falcon design and such. Why they were not included in the portfolio back in the day, I have no idea.
As Yoda sprung up out of the need to complete Luke's training after George decided to kill off Ben during filming, (notice Obi Wan is in the medal ceremony painting) I don't think he's showing up.
