Bob, my take on the article is that 400,000,000 million Post cereal cards were printed in 1961 and that 800,000,000 cards (Post and Jello combined) would be printed in 1962. I'm sure more Post cards were printed in 1962 than 1961, which would leave less than 400.000.000 Jello cards printed. Based on the current availability of 1962 Post cards compared to 1961 Post cards, I would guess that Jello card production was much less than 100,000,000. Pretty interesting article. I hope you find one for the 1963 set as well.
