This was purchased around 2007 or 2008 at the Mitsuo Aida Museum in Tokyo. I welcome questions and price negotiations. Please feel free to ask. It will be shipped from Aichi Prefecture via Kuroneko Yamato. Thank you. The "Issho Benkyo Issho Seishun" (Life is a continuous study, life is eternal youth) is a hologram. At the museum in Yurakucho at the time, I believe it was priced at 15,000 yen or 12,000 yen, which was higher than other items. It is also large in size.
