This is a set of souvenir plates from a sumo wrestling box seat that I found while cleaning out my relatives' house. It includes one large plate and five small plates. My grandmother apparently went to sumo wrestling matches often in the Showa 40s to 50s (1965-1975). Sizes: Small plates approx. 12cm, Large plate approx. 22.5cm Made by Wakao Shoten in Tajimi City. I am also listing another identical set of plates. Although it is a new, unused item, it has been stored for a long time. Please refrain from purchasing if you are sensitive to this. No returns. Material... Porcelain/Pottery Shape... Round plate Item Type... Set of 1 large plate and 5 small plates
