Perhaps they are both having a similiar issue because there was something going wrong when these were printed? Like each were from a different batch but the printing process usually contained an error. It would be nearly impossible to find those few decks per batch, and expensive to kill the whole batch for just a few decks. I am only speculating, I have no idea.
Of COURSE it was a printing error! The ink doesn't just move around on the paper after it was printed, does it?
It's not impossible they were part of the same batch, since there was probably only one batch printed - it was a promotional deck for a tobacco product, not a regular-production item like Bicycle Rider Backs. They don't usually get printed in large numbers.
It could even be possible that depending on the precise similarity of the errors, they were printed within seconds of each other on the assembly line. Quality control doesn't check every pack, just a random sampling, and the higher the "Q" grade number, the lower the quality control used in its production. I'm pretty sure they didn't use Q1 controls for this deck - it's pretty expensive compared to the lower levels (they go down to Q4, I believe).
