Vintage Onyx Perpetual Desk Calendar with Pen Holder

This item is a vintage perpetual desk calendar and pen holder set, mounted on a polished piece of variegated green onyx. The base is rectangular with visible natural banding and swirls characteristic of onyx, suggesting a polished finish. The calendar component is prominently featured on the left side of the base. It consists of a brass-toned metal housing with a spherical or globe-like element at the top, displaying what appears to be a stylized map with latitude and longitude lines. A numerical display, showing '6' in the image, is visible through an aperture on the front of this globe. Below the globe, there is a rectangular mechanism featuring two visible rollers or dials, likely used to change the month and day, indicated by text such as 'MAN' and 'MON' (possibly 'JAN' and 'MON', or similar abbreviations for month and day). The brass-toned metal exhibits a warm, aged patina consistent with its likely vintage origin, and some minor tarnishing or wear is visible, particularly on the edges and raised areas. To the right of the calendar, there is a brass-toned pen holder with a somewhat ornate, possibly knurled or textured, base supporting a simple, slender pen. The pen itself appears to be brass or a similarly colored metal, with a thin shaft. The overall aesthetic suggests an early to mid-20th-century design, likely from the Art Deco or Mid-Century Modern period, often found in professional or home offices. The craftsmanship points to a manufactured item, with the stone base adding a touch of natural elegance and stability. No distinct maker's marks are clearly discernible from the provided image.
