I wish I knew, I think they're absolutely gorgeous and the fact that they're Disney adds more to my appreciation! I really wish I could help you out but I am interested in this as well. I was hoping I could find them in a few weeks at one of the WDW art stores or at the World of Disney in NYC but my hopes aren't high.
I do have the images saved on my computer from google image searches and I have kept the Scarlett Johansson and Julianne Moore/Michael Phelps ads I found in my Vogue mags.
