ETF - CBS 1941 Progress Report on Color TV

Progress Report on Color Television

These pictures are from a November, 1941 document from CBS entitled "Progress Report on Color Television", a 100 page book from the collection of a retired Philco engineer. This is probably the earliest discussion of color discovered to date other than the Bell color experiments from 1928. Thanks to Dave Abramson for providing them to us.
