Almost 40 years after breaking up the first "boy band" is still relevant in today's music world and having their signed "Sgt. Pepper's Lonely Hearts Club Band" album bring in $290,500 at a Saturday auction proves it.

The auction was conducted by Heritage Auctions in Dallas and after a fierce bidding battle the unidentified buyer, who was thought to be from the Midwest, wrote the check for the astonishing amount for the famed and very sought-after LP.

"I consider this to be one of the top two items of Beatles memorabilia I've ever seen- the other being a signed copy of 'Meet the Beatles' [the band's second album released in the U.S.]," Perry Cox, a Beatles expert, stated on Heritage Auctions' website. He added that the singed album cover was "extraordinarily special."

"The previous record for a signed Beatles album cover was $150,000, which was paid for a copy of "Meet the Beatles," according to reports from The Hollywood Reporter.

Not only did the $290, 500 price tag scatter the record, it also brought it $260,500 more than the "experts'" estimate.

"With my being thoroughly immersed in Beatles collectibles for over 30 years, it takes something extraordinarily special to excite me," said Beatles' aficionado Cox, according to clickliverpool.com.

The album includes a high-glos cover and gatefold, and was autographed by the Fab Four (with each member signing next to their picture on the inside fold-out of the record cover), close to its release in June 1967.

Even though the "experts" were shocked, looking back at the history of Beatles items, they shouldn't be.

In June of 2010, the lyric sheet of the song "A Day in the Life" (a song on the "Sgt. Pepper's Lonely Hearts Club Band" album), which was signed by the unofficial frontman, John Lennon, was sold for $1.2 million at an New York auction.
