Rare! Showa Retro Mitsui Bank Commemorative Item Set of 3 Plates Plastic Diameter: 13cm Birds, Crescent Moon, Flowers The designs are very cute. These plates are commemorative items from Mitsui Bank (now Sumitomo Mitsui Banking Corporation) and are very retro. I searched for images, but I couldn't find the same ones, so I don't know how many types there were. There are no noticeable stains, but there may be minor scratches that are not very visible. There is a small shine on the upper right of the flower plate. Please check image 8. I think they are probably over 40 years old. #ShowaRetro Plates #OldDishes #MitsuiBankCommemorativeItem #RetroTableware
