Thanks Steve.
I probably won't be opening many more. Have multiple complete sets for 1970 and 1971 so don't really need any cards from those years.
Will slowly post some cards I have pulled from FB packs I have opened since the late 90's. My general motto is when Im lucky enough to obtain a lot of packs from same year series etc I open one for "research".
Sent a 1968 first series wax pack to PSA for grading years ago, came pack questionable so I opened. Pulled a PSA 9 on a Tommy McDonald card, 2 posters instead of one as advertised and this. Back edge has a small chunk missing or it would be mint:
