Its really a brilliant drawing, wonder who did it ?(maybe done in the 60's to show how the Beatles would age in 30 years ? )
Here's a few by a woman named Shannon who does some of the best Beatles artwork out there. I'm sure some of you are familiar with her. She's unbelievable, all of her paintings are beautiful. Her website is www.theshannongallery.com, and there's tons more on the site.
