I finally found the Easter Egg in the Hard Rock Memorabilia collection. It used to be on the button of Sinatra's tux. Now it's on Paul McCartney's letter to a Miami cop who server as a body guard. It's on the envelope. Inside that, zoom in on the Paramount, then on the marquee, where you can get up close and personal to some Beatles bobble heads.
This is more family friendly than what they showed at Mix earlier this year, with nudies of John and Yoko and some bizarre unused album covered with slabs of meat and baby doll heads.
Actually the "Butcher" cover of the Beatles album Yesterday and Today was released in the US in 1966. It caused such a controversy, they had to put a big sticker over the albums that had not sold.
If you have one of those albums, sans sticker (or ever having a sticker), sell for over 10 grand.
Here's a direct link to the Beatles "Butcher Cover" on the Hard Rock memorabilia site. Very cool piece and a great backstory.
