I found Waldo! Just kidding, but I found Indiana Jones. I also doubt, that the sprites on the left side of him, are part of this Star Wars game.

Edit:

I did the same for the Indiana Jones game: https://i.imgur.com/c1kKfV7.png

Edit 2:

Well, they're part of the game according to http://starwars.wikia.com/wiki/Star_Wars:_Yoda_Stories:

>Indiana Jones is featured as an easter egg in a mission, as a sequel to a mission in Desktop Adventures. His similarity to Han Solo is remarked upon.
