Is Leave It to Beaver (1957-1963) still in memory as an icon of the pre-Sixties era of American culture?

Or as contemporaries like My Three Sons (1960-1973) fall out of memory (I remember it from Nick at Nite, which was the retro rerun late nite block from the early days of the normally child-targeted cable TV station Nickelodeon) is it looting their corpses to be the era’s last signifier standing?
