These photoes are very big sized posters (may be) on the railside wall ( near ceiling) in Mitsukoshi-mae subway station on Hanzo-mon line. A lot of people must remember it. I wander what each meaning of them (for example photo 1) and what for the purpose, for long time.

Today, I was thinking  about photo 1 while I saw other poster (for example photo 2 ). And I thought photo 2 meant “Be careful  falling down from platform”. And then I went back to photo 1, I guessed it showed ” Be careful drop your bag down” as like as photo 2.

I was glad that I got the meaning of photo 1 and 2 untill I saw photo 3.    2016/10/9
