This appears to be at the Polychrome Yonkers plant. Dr. Ooba is to the left of Mr. Halpern. Mr. Gumbinner in far right. Behind in the center is Ray Lauzon and far left is Mr. Yonezawa of Fuji. Mr. Yonezawa and his technical group spent weeks studying technology after the signing of the licensing agreement. Dr. Ooba probably came to inspect the progress.
Here is the rare picture of Mr. and Mrs. Halpern at a party hosted by Fuji. Dr. and Mrs. Ooba to the left. I do not recognize any other so this must be really old picture of perhaps at the signing ceremony in late 50'
