1909 Theodore Roosevelt Portrait Autographed to Charles Doolittle Walcott, and the Charles Doolittle Walcott Prize Medal. 4 3/4 x 7 1/4 inch sepia photograph of the President, facing, with handwritten inscription in the margin below: To Chas. D. Walcott / with the regards of / Theodore Roosevelt. To the right is the date March 1st, 1909. The photograph is mounted in an 11 x 14 inch brown cardboard frame of Harris & Ewing of Washington, D.C. The photograph is essentially mint, the frame appearing excellent from the front but with a small chip missing from the cardboard backing - which is not detectable from the front. When Roosevelt signed this, he was in his final week as President, and Walcott was on the eve of his spectacular discovery of fossils of soft-bodied Cambrian animals in the Burgess Shale of British Columbia - his original quarry so important that the site is preserved today as a UNESCO World Heritage Site. The Charles Doolittle Walcott Pre Cambrian Research Medal, by famed engraver Laura Gardin Fraser, has been awarded every 5 years since 1934 (except for a hiatus during WWII) to honor and promote research and study in the fields of Precambrian and Cambrian life and history. Seldom seen, this medal features a bust of Walcott facing right, his name, and the title of the medal. The reverse of the 77 mm bronze medal presents a detailed image of a fossil trilobite as well as the legend NATIONAL ACADEMY OF SCIENCES. The medal is About Uncirculated. (Total: 2 pieces) From the Richard Jewell Collection.
