My sister got me a Cyberdyne Systems T-shirt for Christmas - I was really pleased and very surprised to say the least. But if it was a Santini Air T-shirt I would have probably burst a vessel.
Mark, I noticed on one of the T-shirts on your link, it features the top part of the original 'movie' poster artwork. I have a full poster proudly framed on my wall, fantastic thing, but on the T-shirt you can clearly see the pilot, on my poster there is definitely no pilot, just a shadowy shadow (Shadow of the Hawk?). I wonder if the 'pilot' was inked in later in some versions of the poster/image?
