A while back, there was a discussion in another thread about whether Topps would include packs from different series in the same box, or even cards from different series in the same pack, in the days of issue by series.
Just saw this video today - the Zimmermann is from series 2, and the rest from series 1.
Thoughts on this? Legit?
