This striking vintage Art Deco style desk set, dating from circa the 1930s to 1950s, features a polished black Bakelite (or early faux-marble lucite) base paired with dual chrome-plated trumpet pen holders and a central mechanical perpetual calendar. The classic rolling drum calendar mechanism is fully functional, adjusting the day, numerical date, and month via the textured side knobs, and currently shows a clear vintage typography window display. Measuring 22.5cm long by 10.5cm wide, this elegant desk accessory is reminiscent of the high-quality office ware produced during the mid-century by prominent manufacturers like Park Sherman or item styles popular across Europe and North America. It is in very good vintage condition, showing minor surface wear, age-related pitting on the chrome, and light scuffing on the base consistent with age and use, but retains a brilliant shine and excellent mechanical functionality.
