Original Advertising Plaque from the "Schwestern Flöge" Fashion Salon, Vienna – Casa Piccola, ca. 1904.

Emilie Flöge and Gustav Klimt—two iconic figures of the Viennese fin de siècle and bohemian art scene—are uniquely united in this exceptionally rare couture house sign from early 20th-century Vienna. Measuring approximately 33 × 23 cm, this original advertising plaque is a tangible relic of the legendary Schwestern Flöge fashion salon, designed in 1904 by Klimt himself for Emilie Flöge’s haute couture boutique.

Emilie Louise Flöge (1874–1952) was a pioneering Austrian fashion designer, entrepreneur, and muse to Gustav Klimt, one of the most celebrated painters of the Vienna Secession. At the age of 30, she founded the Schwestern Flöge salon with her sisters Helene and Pauline, located in the Casa Piccola building at Mariahilferstrasse 1B, Vienna’s fashionable shopping district. The salon’s interior was designed by Josef Hoffmann, a leading figure of the Wiener Werkstätte, and showcased avant-garde Art Nouveau fashion that reflected the collective’s aesthetic ideals.

This original couture house sign - possibly displayed in the salon’s window or reception area - isnew a rare surviving artifact from the Flöge fashion house. Crafted in Klimt’s unmistakable style, it features gold lettering and gold print on leather, reading: “Schwestern Flöge • Vienna • Casa Piccola • Mariahilferstrasse 1B • Telephon 1621”. The sign remains in good condition, with expected wear to the gold surface, minor scratches, a missing corner, and light staining - consistent with its age and authenticity.

What makes this piece truly extraordinary is its direct connection to both Gustav Klimt and Emilie Flöge, as well as its embodiment of Wiener Werkstätte design principles. Very few objects from the Schwestern Flöge salon have survived - aside from a handful of dresses and a chair housed in museum collections. This sign is not only a rare Klimt-designed artifact, but also a testament to the innovative spirit of Vienna’s Art Nouveau fashion movement.

Collectors of Wiener Werkstätte memorabilia, Klimt ephemera, or historic Viennese fashion will recognize the exceptional provenance and rarity of this piece. It is a museum-worthy object that bridges the worlds of fine art, design history, and avant-garde couture.
