Hi Gang:
Ken, and I along with other advanced Post Cereal collectors have been doing research on the 1960 Post Cereal set for quite awhile. Ken laid out all the findings in the above post.
We feel it is very significant that a new variation has been found in the set. The fact that the Gifford was the only "card" issued on both size boxes of Grape Nut Flakes caused the variation Ken described.
Below are links to scans of both versions. I am having trouble attaching scans to this post. If that changes I will update.
Note the location of his signature.
