You can see these pictures at the Kansai Airport station of the Nankai train.
There are four pictures.
All are from famous pictures of ”The Gleaners”, “The Mona Lisa”, “The Birth of Venus” and “Moulin de la galette”.
Those are made up of 320000 used train tickets which were collected at Namba station, and posted by manual labor.
That was the best part of this exhibit.
