This is a Showa-retro ramen bowl. This ramen bowl from Kakusen Toen features a Showa-era design with a panda pattern. Banker, the character of the now-defunct Sumitomo Bank, was also a popular novelty item back then. This nostalgic ramen bowl is a small size, so it's perfect for children. I think it's a rare item. (The bottom part doesn't seem chipped, but it's a Showa-era item, so it's a little bumpy. Please refer to the images.)
