Yenra Details from Big Sister Cosplay Vintage Diving Helmet: A close-up view of an old diving helmet, likely from the early 20th century. The helmet is crafted from metal and features a circular shape with a domed top. A prominent feature of the helmet is its large, round eye port, which is surrounded by a metal frame adorned with rivets. The eye port has a mesh-like pattern etched into it, allowing for visibility while submerged in water. The helmet's surface exhibits signs of aging and wear, including rust spots and scratches, indicating that it has been used extensively over the years. The overall appearance suggests that this diving helmet was once used by a professional diver or naval officer during World War I or II. In addition to the diving helmet, there are two objects visible in the background: a blue object on the top right side of the image and an indistinct shape on the bottom left side. These objects appear blurry due to shallow depth-of-field effects, making it difficult to discern their exact nature or purpose. The background itself is out of focus, with no distinct features or colors visible. The overall atmosphere of the image suggests that it was taken in a museum or historical collection setting, where artifacts like this diving helmet are preserved and displayed for educational purposes.
