Thank you for looking. This is a 5-yen discount bromide from Shochiku's monster movie, "Gamera vs. Guiron" (or "Attack of the Monsters" depending on the region). It comes with the original bag that the card was in. The front of the bag has a picture of Guiron, and the back has the text "Tokyo Marusho" and "Approved by Shochiku Films". While people often keep the cards, it's rare to find the bag in relatively good condition. As you can see from the photos, it is a vintage item, so I ask that you understand it as a collector's item. Thank you for your consideration.
