The pandas in the postcards are: Top left: Yuhin & Rauhin Bottom left: ? 1st birthday photo (probably Saihin) Top right: Kaihin & Youhin Bottom right: Eimei Except for the bottom left card, the postcards were originally connected, so they have been separated at the perforation. Therefore, there are traces of cutting on the edges. Also, the bottom left card does not have a stamp area, etc. (See photo 2) They have been stored in a dark place, but there is yellowing, scratches, and creases due to aging. Stored at home by a private seller. Please refrain from purchasing if you are sensitive to these issues.
