Nautical Porthole Frame with Etched Shipyard Illustration

This item is a circular nautical-style porthole frame featuring a central artwork. The frame is constructed from a heavy cast metal, likely iron or aluminum, finished in a matte olive-drab or industrial charcoal paint. It exhibits authentic maritime design elements, including a hinged outer ring, a top-mounted wingnut latch (butterfly bolt), and several decorative hexagonal bolts spaced around the perimeter. The central art piece appears to be an etched or engraved woodblock-style print on a parchment-like substrate, depicting a historical shipyard scene with laborers engaged in shipbuilding. The artwork uses a muted color palette of blues, greens, and browns. Note the visible crack in the print on the left side, indicating possible drying or mechanical stress to the parchment. The frame itself shows minor scuffing and paint wear, particularly on the edges and bolts, suggesting a piece designed for an industrial or vintage maritime aesthetic, likely mid-to-late 20th century. The craftsmanship of the frame is robust, successfully mimicking functional naval hardware.
