Despite the fact that the band never played in Argentina, an obsessive fan has put his country on the Beatlemania map.
Following the examples of museums in the band's native Liverpool and their early haunt Hamburg, a third major collection has opened to the public in Buenos Aires.
Besame mucho: A new Beatles museum in Buenos Aires has opened with more than 8,500 items for exhibit
The eclectic collection is the work of self-confessed obsessive Rodolfo Vazquez, a 53-year-old accountant who became a fan at the age of 10 when he got their album Rubber Soul.
Since then he has collected everything he possibly can related to the Fab Four and has amassed more than 8,500 items.
In 2001 he was recognised by Guinness World Records as having the planet's largest collection, with a hoard of 5,612 items.
But his haul has kept growing and his museum, which opened this month on Avenue Corrientes in a touristy area of Buenos Aires, is only able to hold a quarter of it.
'The idea is to show my collection permanently,' said Vazquez.

Every Little Thing: Not content with his huge collection, Vazquez also has a nightclub called The Cavern
'In a year I would like to rotate the items on display with others from my collection.
'Otherwise all of it would be closed into boxes and trunks without anyone being able to enjoy them.'
The museums in Liverpool and England may have more significant items on display, while private collections such as those of Julian Lennon - John's son - have more intimate pieces, but the Argentinean museum stands out for its sheer weight of numbers.
Vazquez claims he doesn't know the total value of his private collection, which includes record covers, autographs, toys, original pictures, concert programs, and cups and plates with Beatle images.
There are objects for all tastes: a Beatles wig that says it adjusts to any head size, and signed pictures of the four musicians.
His most prized object include 64 boxes of chewing gum in the form of miniature albums that allude to the 16 Beatles records and four music boxes with figures of John Lennon, Paul McCartney, George Harrison and Ringo Starr.

Vazquez even has certified copies of the quartet's birth certificates.
In one display case, there's a brick – one of about 5,000 pulled from the demolition in 1983 of the original Cavern Club.
There's also a hunk of the stage of Hamburg's Star Club, a strip club where the musicians worked as the house band, at that point with Pete Best as drummer.
Alongside that is a pair of drumsticks signed by Best, who was replaced by Ringo Star in 1962.
There's even a piece of the floor of Strawberry Fields, a Salvation Army orphanage near Lennon's boyhood home whose name inspired the 1967 psychedelic rock tune Strawberry Fields Forever.
And Vazquez continues to accumulating objects, either buying or trading for them with other collectors around the world.
'In Britain and Spain I found many fans,' he said.
'By mail I've received things from Japan, Britain and Brazil, and I'm still doing it.'
His Beatles obsession isn't limited to his museum either.
Each year, Vazquez organizes a Beatle Week, in which cover bands from around Latin America compete to be named the best imitators. The winners travel to a Liverpool music festival.
Many such bands play in Vazquez's bar named in honour of The Cavern Club, the Liverpool nightclub where the band got its start.
But nearly 2,000 people have visited since the museum opened on January 3 and Vazquez says he is aiming for some special items that would complete his life's work.
'What I am missing is to shake hands with Paul McCartney and Ringo Starr, hug them and chat with them a little bit,' he said.
'It is what would complete me and I would be the happiest collector on earth.'
