Only Yesterday (Omoide Poro Poro) is a Studio Ghibli film by Isao Takahata released in 1991.
I am immensely pleased and honored to have any cels from a Studio Ghibli production.
It is a wonderful film of a 27-year-old Tokyo office worker, Taeko Okajima, reflecting on her life during a visit to her sister's in-laws in the countryside. She remembers her childhood in various flashbacks throughout the movie.
