What was the best fight card of the 1950's?

Looking back at the complete cards for Archie Moore, Joe Brown, Kid Gavilan, Marciano, etc. fights in the 1950's I was a bit surprised that the supporting fights were all 4 and 6 rounders of mostly no-namers or regional up and comers. The first Marciano-Walcott bout did have Oakland Billy Smith and Cleveland Williams on the undercard but each in 6 rounders against nobodies.

So, what was the best complete boxing card of the 1950's?
