John Lennon celebrated with release of commemorative stamp
The stamp features a photo of Lennon taken in 1974 on the roof of his Manhattan apartment building.
John Lennon's moptop, round glasses and grin will now adorn a US stamp.
Hundreds of fans joined Lennon's widow, Yoko Ono, and their son, Sean Lennon, celebrating the US Postal Service's release of a stamp honouring the late Beatle at an event in New York's Central Park.
"I know that my father would have been really thrilled to be accepted, officially in this way, on a stamp," said Sean Lennon. "About as official as it gets, I think."
The commemorative stamp features a photo of Lennon taken in 1974 on the roof of his Manhattan apartment building by photographer Bob Gruen, who also spoke at the event. The stamp is designed to look like a 45-rpm record sleeve.
"Everybody loves to listen to John's songs and I'm very proud of it, but also the fact that this day, Imagine and you guys are here. It's incredible," Yoko Ono said.
She also joked about the blame she gets for breaking up the Beatles.
"If John just went with me and then he began, 'La La La, Da Da Da' or something like that, people say, 'Well, that's Yoko's fault,'" she said. "Well, it's always my fault."
The crowd received her warmly and gave her a standing ovation.
"I always knew how much he loved her," said Donna Gallucci. "A lot of people didn't understand that."
After the event, people lined up to buy the stamps and enjoy one more day of Beatlemania in New York City.
Ms Gallucci said: "He was so much a part of the city, so much a part of the park."
