Series 1 of the set had like 6 printings. The first 2 printings had the brown camo in the shield, the packs even had it on the wrapper, followed by the yellow lettering. Bit confusing to try to understand this set, as there are also UK, and Australian versions of the set. Also a couple different factory sets were made with different stock and finishes.
I wouldn't consider any of them to be parallels, as the other 2 series don't continue that trend. I only know of 2 printings of each of them with 5 variations in series 2, and 2 errors with corrections in series 3. One day I'll try to add what I have, but need to get them all together before I do.
