His pictures were frequently published without attribution, he rarely featured in press reports, with only brief mentions in contemporary books.[12] He however earned a reputation among Egyptologists as the finest archaeological photographer of the time.[27] Carter valued his work highly, describing his photographs as "of outstanding beauty as well as great archaeological value".[28] In May 1923 Carter wrote to Albert Lythgoe, who had agreed the loan of Burton from the Metropolitan concession, confirming that Burton had completed his work "in a splendid and admirable manner. In fact, I do not know how to praise his work sufficiently. He had a colossal task which he carried out to the end in the most efficient manner possible, and I should like to convey through you my most sincere gratitude to your trustees and Director for his good aid."[29]
