He and his brother Ted documented the trip in their book East of the Sun and West of the Moon. Several trophies collected during this expedition are on display in the Field Museum of Natural History in Chicago. This expedition, financed by Museum trustee James Simpson, is sometimes called the "James Simpson-Roosevelt Asiatic Expedition of the Field Museum of Natural History".
