“Soshu Shichirigahama” (Shichirigahama in Sagami Province) from Katsushika Hokusai's "Fugaku Sanjurokkei" (Thirty-six Views of Mt. Fuji).
Shichirigahama is a beach located in Kamakura City, Kanagawa Prefecture, but it seems to have been arranged from the actual landscape, with Koyurugi Misaki in the center of the painting large and Enoshima on the left extremely small.
Horizontal and vertical trimming versions are available.
Both iPhone and Galaxy cases are available.
