This is Yoko Imamura's Pechako-chan handkerchief. It was serialized in the Shogakukan magazine, Shogaku Ichinensei (First Grade Elementary School), from 1968 (Showa 43) to 1978 (Showa 53). It's from around 1970 (Showa 45). The outer bag it came in is not included. The size is approximately 28cm long and 27.5cm wide. It has been stored at home, but it is old, so there are wrinkles, stains, dirt, and creases. Please understand. I think it's difficult to obtain now. How about it?
