Once again, E-Sylum readers show their creativity. Whether it turns out to be provably true or not, Marc Ricard.s suggestion of .Centennial Art Gallery Exhibitor. for .C.A.G.E.. is pure deductive brilliance. I had always narrow-mindedly assumed that it referred to the presenter without ever considering the possibility that it could just as easily refer to the awardee. Thank you, Marc! If nothing more definitive turns up, I will include your idea in the book and invite readers to continue the hunt.
