This 1906 postcard depicts the Windsor Hotel in Jacksonville, Florida. The multi-storied hotel, a representative example of early 20th-century Florida resort architecture, features a central tower and extended wings. The colorized image, produced through a photochrom or lithographic process by E.C. Kropp of Milwaukee, highlights architectural details including gables, arched windows, and landscaping featuring palm trees. An unpaved street with telephone or telegraph poles is visible, documenting Jacksonville's infrastructure at the time. The postcard exhibits color fading consistent with period printing techniques. Postmarked March 15, 1906, the postcard was sent from Jacksonville to Miss Lila Higgins in Hellflut, Massachusetts. The sender, identified as "Yuss," included the notation "Jacksonville, Fla." The postcard features a divided back, conforming to postal regulations implemented at the time, and bears a one-cent Benjamin Franklin stamp, predating the 1917 postal rate increase. E.C. Kropp produced chromolithographic and photochrom postcards depicting hotels and landmarks for the souvenir market. The destination of Hellflut, Massachusetts, represents a now-uncommon place name. The postcard, reflecting imagery, publisher information, and postal history, is an example of period ephemera, useful for understanding aspects of early 20th-century American social and material culture.
