More than 45 years after the Beatles first invaded the U.S., snapshots of their historic 1964 tour by the late Curt Gunter have just arrived at New York's Morrison Hotel Gallery. The group made their first live American television appearance on "The Ed Sullivan Show," broadcast from New York on CBS (not pictured). 73 million tuned in to watch the show. The candid photos capture the young Fab Four in intimate and lighthearted moments, just as Beatlemania was reaching its most fevered pitch.
