With every great discovery undoubtedly comes the realization that what you're seeing is real, that it actually exists. In the case of TUTANKHAMUN: THE GOLDEN KING & THE GREAT PHARAOHS, the "real" is rationalized through the docuphotography of companion exhibit WONDERFUL THINGS: THE HARRY BURTON PHOTOGRAPHS AND THE DISCOVERY OF THE TOMB OF TUTANKHAMUN. Less than a century after Tut's unearthing, this exhibit of 50 photos highlights the discovery, excavation and genius that went into bringing a landmark of world history to Atlanta's humbled doorstep.
