This along with the 1965 Topps Football are the first sportscard sets I remember.
Hey TC, I don't know if you realize this but back in the day the Cowboys were quite good. I was watching the 1967 Eastern Conference Championship beween the Cowboys and the Browns and Dallas won 52-14. This win put them in The Ice Bowl as Green Bay beat the Rams in the Western Conference Championship that same weekend. I know after 30 years of futility the fact that the Cowboys were once good comes as a surprise to you but it is in fact true!.
And to top it off their QB's name did not rhyme with Gak and no one had a nose ring. Who knew?
