The faces identified so far are; front from left, Dr. and Mrs. Ooba, legendary founder/ then president Mr. Setsutaro Kobayashi, Mr.& Mrs. Halpern, Mrs. Kobayashi, Mr. and Mrs. Kume of Mitsui & Co.
Mr. Ishihara is far right 3rd row and Mrs. Ishihara is 3rd from the right.
Both Mr. Kume and Mr Ishihara were stationed in New York then. Initial approach to Polychrome was done by Fuji and the follow up was apparently done through Mitsui Trading.
In the same year a team of Fuji technical personnel visited Yonkers to be trained for the technology
transfer. Dr. Ooba headed the team and the member lead by Mr. Yonezawa stayed several weeks for the training.
Far left is Mr. Yonezawa, 4th.. Dr. Ooba, Ray Lauzon, Mr. Halpern, Mr. Ikegaya of Mitsui then Mr. Gumbinner.
