1930 Post Cereal Christy Mathewson

[Eric -goudeyhunter]

I'm doing some background on the 1930 Post Cereal - Famous Americans Mathewson card (and greater set) and need help determining two things:

1) The correct ACC#
2) The card size(s) of the issue

Here's what I've found:

When I look at the original ACC book I see this set classified as F92 (pg 101), which lists the set as: Famous Americans. Most websites and auctions list this set as F278-50. F278 is reserved for several Post issues, but I don't see Famous Americans listed amongst the 26 sets detailed in the original ACC (pg 105).

The second part regards the size of the card. I bought my first Post Cereal Mathewson card 20-25 years ago, and it came attached to the other three cards around it. The other cards had some extensive creasing etc, so I cut the Mathewson apart. I haven't cut apart a card in a couple of decades, but back then it seemed the sensible thing to do. Anyways, that card measures 2 7/8 x 3 3/4.

Last week I purchased another Post Cereal Mathewson and this one measures 2 3/8 x 3 1/4, the size noted on some baseball card reference websites.

Using a 40x loupe, I see no difference in cardboard stock, printing method, ink, or design for these two cards. I believe both are authentic.

Both cards are attached for inspection. Any and all thoughts are appreciated. Thank you in advance.
