theres a book called "like a prince from another planet",there you
get real close ups of his face (in concert in the late 70's),you can see how much he had on.
in that book you even see that he had forgotten to dye his sideburns,they are grey!.a real cool book!
you can get your hands on it at elvisunlimited.com/webshop for $ 25.
it is said that he never left the house without makeup,hehe...don't know if thats true,I don't think so. But he did use it from early on and right to the end.
