sorry, i can't see it. even after blowing it up in photoshop and altering the brightness heavily. which would usually show up anything. there may be some kind of pattern, but i can't say it's definately the decal.

take a look at this moon landing photo. some would have you beleive the pic was faked due to absence of stars. but if we alter the brightness a lot, we see that the stars are there, just that the glare stopped us from seeing them (although i still have my doubts, for other reasons, to be honest with you). the same technique should have worked with the headstock, were the heastock and the decal even slightly different colours (ie red and black). we should have seen a much wider difference as we upped the brightness
