I absolutely loved this series as a kid & remember it as being one of my very favorite 70's Marvel titles. I snapped up every team-up, giant-sized-special, two-in-one, etc ... w/ Shang-Chi in it. From back-story to his regular adventures, this book was special. It hit around the same time David Caridine's Kung-Fu show was huge along w/ Bruce lee movies. Paul Gulacy's art in the book was just outstanding & Mike Zeck picked it up later w/ splash-panels that just blew my mind. Doug Monech wrote the lions' share of the tales as I recall.
There was a great Giant-Sized Spiderman where both Spidey & Shang-Chi jumped off the top of the Empire State Building that still pops into my mind today.
Master of Kung-Fu had a strong S.H.I.E.L.D-type spy thing going on in its backstory w/ Shang-Chi having a pretty cool collection of companions.
This & Tomb of Dracula stand on the same level in my opinion as absolute classics of 1970's Marvel. As good as it got back then. Shang was both hunted & hunter in this series as his Dad, Fu Manchu, threw everything he had at his son.
I can not recommend this comic enough & am sure it will be, like Ennis' Punisher Omni, one of the impossible to find Marvel Omnibus of the future. Buy this one. I so am.
Mike Zeck's art on Shang-Chi, The Master Of Kung-Fu .... Fantastic!
