Yamamoto finished the Western painting course at the Faculty of Fine Arts at Kyoto City University of Arts in 1978. With her distinctive style in which she seems to sketch memories and images of articles on the table, encounters with people, and souvenirs of journeys on the copperplate, she has won numerous awards in competitions held in Japan and overseas. She has a reputation for the poetical narrativity underlying her works and a sophisticatedly refined style and exerts them in book design and illustrations, too.
These are razors, the ones on the left for men and those on the right for women. On the edge of the two images, the men’s razors are bordered with coarse whiskers and the women’s with soft downy hair. Yoko Yamamoto began producing copperplate prints with alphabet types or small daily articles as her motifs and this print amply conveys her style in those days. First of all, she stamped the razor in the lower left. Then, using letterpress types, she impressed the letters all over the image and finally drew each one of the razor shapes by hand. The boxes are represented in serigraph and frottages of the women’s razors appear in red. The motifs are repeated in a gentle fluctuation, providing the image with a characteristic rhythm and vigor. The title indicating the usage for men (Papa) and women (Mama) is a pun on the American folk group The Mama’s & the Papa’s.
