I remember getting this comic for the princely sum of 25 cents back then (and it was a lot back in the 1960s -- coke bottles were only selling for 2 cents each, so I had to find half a flat of them to buy the comic), but thankfully there was no tax on a quarter (yeah, that's what's really unbelievable at this point).
I loved Goliath's new costume back then, and I figured Black Panther was toast going up against the Hulk. And Hawkeye squaring off against Iron Man? Please!
