Original vintage advertising sign for Caffè Guglielmo, one of the historic Italian coffee brands, featuring the iconic archer inspired by William Tell, introduced by the company in the late 1960s as part of its renewed advertising identity. The graphic belongs to the golden era of Italian commercial design, when strong visual mascots and bold colors were widely used to make café and bar signage immediately recognizable from the street. This example is likely dating from the early 1970s and was originally installed outside a bar, café, or coffee shop. The sign is made of folded sheet metal (approx. 2.5 mm thick) and retains the original corner mounting holes, confirming its outdoor commercial use. The central bend is characteristic of signs mounted with wall spacers, allowing the panel to stand slightly away from the wall and increasing its visibility. A particularly attractive feature is the decorative border with concentric circular pattern, a distinctive graphic element used in several Caffè Guglielmo advertising designs of the period. Dimensions 60 × 48 cm (22 x 17 inches ca.) Condition Good vintage condition with authentic patina and signs of age consistent with outdoor exposure, which enhance the character and authenticity of the piece. Original coffee advertising signs are increasingly sought after internationally, as coffee culture represents one of the most recognizable aspects of Italian lifestyle. Examples from Caffè Guglielmo, especially in this large format and with the complete archer graphic, appear relatively uncommon on the collectors’ market. A striking decorative piece, ideal for collectors of vintage advertising, coffee memorabilia, bar décor, or industrial interior design.
