Four Japanese Stamp Catalogs: "1993, 1998, 2003, 2007" & Three Commemorative Stamp Placemats - Retro I am selling these items as I organize my parents' house. The placemats are made of plastic and are quite old, dating from Showa years 57, 58, and 59 (Ministry of Posts). The stamp catalogs show signs of wear, such as folded pages, writing, and corner damage. There may also be some browning due to aging. The placemats are unused but have been stored without packaging, so they have some minor scratches. Please understand and acknowledge that these items have been stored by an individual for a long period of time.
