In those days when the average monthly wages for salaried workers was about 50 yen, ITO's salary as an engineer was higher than the average but the money he managed to raise by selling his expensive camera and others was short of the 3 million yen.
当時の勤め人の平均月給は五十円程度の時代で、伊藤はまだ会社勤務の技術者だったため、平均月給よりも高給を得ていたが、所持していた高価なカメラなどを処分しても三百円に足りなかった。
