[giorgio]

Hi, I hope I am in the right place. I am looking for a picture in high def for a gift I want to do for my wife. She is obsessed with the Muppets and i want to print and frame a nice picture of all of them together.
Any suggestion? Any special website? I don't know much about them, I even have hard time to spell muppets, I wrote it few time with the a instead of the u I really need some help.
Thank you all
G.
