The fellow Barry Sloate and I know is a Chemical Engineer who specializes
in all forms of paper restoration. In fact, during the late '80s he did some
card restoration. The quality of his work is unbelievable. His "film" theory
regarding the fronts of the T206 cards is not to be discounted.
Most vintage BB cards are composed of two layers of thin cardboard laminate.
And, indeed the color printing process required 4 - color inking stages.
Pre-printed front sheets were laminated onto pre-printed back sheets of cardboard.
However, the T206 printing process appears to be different. I have had T206
cards whose fronts have disintegrated into small flakes due to aging (sun expo-
sure, heat, etc.). I would say this type of deterioration reinforces this "film"
printing theory.
