So the main issue is that at "third party" would profit? So self-tattooing would be okay, as there is no money going to a third party?

Scurv, that's a hard one, as few pics are clearly labeled as being "red era". Are you looking for fantasy or 40k reference material, you could try googling on the contempory edition of the rules? (2nd for 40K and, what is it. 4th or 5th for fantasy?)
I think your best bet, though, would be to go through a stack of old White Dwarfs.
