100% fake.
Check bubble size ( now this can vary for Taiwan examples- Stormtrooper is not one )
This is the fake:
bubble part goes from the middle of the racetrack to the edge of the red figure area.
Compare to Mark Yeo's: http://www.imperialgunneryforum.com/t4619-my-kenner-12-back-run-a-work-in-progress
bubble only covers red area, ages 4 and up font is wrong, other tells white cardstock, punch position.....
