These are "Nameneko," which were incredibly popular in the Showa era! There are small spots of dirt. I've circled them in photos 3 and 4, but there are also other small stains that can be seen if you look closely. Please understand this before purchasing. "Namenna yo" (Don't mess with me) is cool and cute ♡ In this modern age where AI can do anything, I wonder how these cats were photographed back in the Showa era? This is a very valuable envelope from about 40 years ago. Rare item Showa retro Cosplay cats Bōsōzoku (motorcycle gang)
