These are laminated cards and bromides of Showa-era idols. The Shonentai address book is in beautiful condition. I believe these are quite rare items that will likely never be obtained or appear again, so they are highly recommended for collectors. I researched and found the following people: Shonentai, Yoko Minamino, Hikaru Genji, Chiemi Hori, Onyanko Club, Noriko Kaise, Mako Kikuchi, Yukiko Okada, Yui Asaka, Akina Nakamori, Shizuka Kudo, Kazumi Morohoshi.
