60 pieces, i.e., nearly half of all the pieces, were basically copies of Kiyochika's works, however, Yasuji modified them to be simpler through omitting people and backgrounds since the painting size was reduced to about a quarter of the original painting size, the postcard size.
全作品中、半数近い60点は清親の作品をほぼ倣った物であるけれども、大きさが元の大きさの4分の１程度のはがきサイズほどになったのを受け、安治は人物や背景を省略、簡潔な描写に改めている。
