A copy of the Beatles' 1963 album Please Please Me, signed by all four Moptops sold for $36,655 on eBay.
When it comes to memorabilia, you can't do much better than early Beatles items. They're an iconic group with millions of loyal fans worldwide. Even fifty-years-later their music continues to have a demand. When you consider their huge fan base and small amount of early memorabilia available. Finding a fully-signed record in mint condition (fifty-years later) is exceptionally rare.
This actually seems like a bargain. I'll bet this album will sell for 10 times as much in a decade.
Bonus fact: The album's title song, "Please Please Me," is probably the most famous song about a blowjob ever recorded.
