For decades WWE fans have dreamed of The Undertaker vs. Sting. 

The Dream Match has never happened but 30 years ago in WCW during the summer of 1990 before Mark Calaway joined WWE as The Undertaker he wrestled as “Mean” Mark Callous and actually went up against Sting...twice.

Although footage of the classic matches doesn't exist a fan has put together a fake simulation of what the match might have looked like:

Sting successfully defended his NWA World Heavyweight Championship against "Mean" Mark Callous (The Undertaker) in their only singles match, held at the Greensboro Coliseum on September 1, 1990. They faced off one other time, in a tag team bout at the Cumberland County Civic Center in Fayetteville two days earlier (Sting and Lex Luger went over Callous and Moondog Rex). No footage of either match exists, but I have used early 1990s clips to create a realistic simulation of "The Icon" vs. "The Phenom". The thumbnail is from a REAL black and white photo of the Sting/Callous match (to which I added some colour).
