Figure 3.4 in the book "Bright Signals," a picture from the Hagley Museum collection captioned "Undated photo of a color television being calibrated once off the RCA assembly line." Courtesy of the Hagley Museum and Library.
The image on the TV is almost surely stripped in mechanically for this shot.
Has anyone ever seen a factory setup step like this, with the image (probably meant to be gated rainbow?) compared to a large photo print?
