From early on, the public reacted very positively—even fanatically—to his character, in what "The Boston Globe" in 1967 described as "Spockmania". Headshots of Spock became popular souvenirs, with the rare ones of the actor laughing the most valuable. Nimoy reported that "within two weeks after ["Amok Time"], my mail jumped from a few hundred letters to 10,000 a week". When he appeared as Spock as grand marshal of a Medford, Oregon parade in April 1967, thousands gathered to receive autographs: "They surged forward so quickly that I was terrified someone would be crushed to death; and then they started pressing against the bandstand so hard it began to sway beneath my feet!" After being rescued by police, "I made sure never to appear publicly again in Vulcan guise", Nimoy stated.
