The Swiss-born American artist Adolfo Müller-Ury began a portrait of Mann in the middle of October 1902. When finished, Town Topics commented favorably on the portrait of its proprietor in its November 27, 1902 edition, writing: "... Mr. Ury's friends will be pleased to note that his work has broadened a great deal in recent months. His portrait of Colonel Mann, particularly, is rendered with considerable freedom and vigor, and in this respect is the best work that the artist has produced. The portrait is fair in color, a good likeness — although the mouth is perhaps unnecessarily severe — and the downy quality of the white hair and beard is especially well painted..." The portrait was exhibited at the Noe Art Galleries, on Fifth Avenue, between January 5 and 19, 1903.
