Age Guessing Card. * Gaki Deka * Dokaben I believe these were received when purchasing paperback books (manga) at a bookstore in the Showa era. The Gaki Deka one is cut off because I applied for a lottery. One of the cards has a fold (see photo 5). Due to long-term home storage, please refrain from purchasing if you are sensitive to imperfections or seek perfection. Since it's a simple check by an amateur, there may be various oversights. Please understand.
