When Mr. Halpern retired in 1981, Gregory von Gruenberg made a photo album for Mr. Halpern. Annelise von Gruenberg, his wife kept his original photos and a photo album. Here is the copy of his color prints. We were all very young then! Thanks Annelise for sharing. For copies of positive slides see HERE.
And thank you very much who helped identify those in the pictures Marge McGill in particular, who combed the old Polyworld to find who's who. There are several we could not identify especially those in production. If you can identify them please let me know. Thanks
