Standing in full Victorian-Romanesque glory against a brilliant Colorado sky, the East Side High School of Denver — later renamed East High School — commands its corner lot behind a screen of mature elms in this vivid hand-colored postcard from the late Undivided/early Divided Back era. The building, designed by architect Robert Roeschlaub and completed in 1889, was Denver's premier public high school and one of the finest examples of Richardsonian Romanesque architecture in the Mountain West; its elaborate arched windows, polychrome brick façade, and mansard-influenced roofline are rendered here in warm reds and greens that still pop after more than a century. Card no. 1726 suggests this was part of a larger Denver views series. The back is entirely blank and unused, with the ornate "Post Card" script header and the notation "Domestic: One Cent / Foreign: Two Cents" — a dating clue pointing to the 1907–1909 window when the undivided-to-divided back transition was complete but postage rates were still being clarified in print.
