Showa Retro Menko (Collectible Cards) - Square Menko Rare Item ◎ Menko from the 1970s (Showa 50s) There are 50 different types. Since there are multiple copies of the same type, there are over 100 cards in total. * Mazinger Z * Great Mazinger * Getter Robo * Brave Raideen They have been stored in a dark room for nearly 50 years. Some are unused, and some show signs of wear. The square menko are mostly unused. Although they are from the 1970s, I personally believe they are in decent condition for menko.
