This postcard sent by Eva also belongs to my Japan Week (1, 2, 3). I just receive it later because it was sent to Spain.
The sender says that the postcard represents the pilosophers' way in Kyoto. The stamp is one of the four paintings of Utagawa Hiroshige chosen for the International Letter Writing Week. The title of the painting is Sparrows and Camellia in Snow, and it was inspired by a beautiful winter poem (See here).
