Kind face, invincible? Rising stone? Colored paper? Size: Approximately 27cm tall, 24cm wide Postcard size: Approximately 15 x 10cm On the back, there is a stamp that says "Aircraft Body Failure Detection Device, Discoverer: Haruzo Morizane." There was a postcard from the 1997 "Aircraft Industry Technology Exhibition" in the photo, so I think it is related to this technology exhibition, but I don't know the details. Long-term home storage item. There are color fading, wrinkles, and folds. I peeled off the address label that was stuck on the postcard, so there are traces of peeling.
