When a proof is a proof

[Abravefan11]

If I am understanding his points correctly I disagree with the following:

"In short, these six men would've been headline-makers in the Southern Association and South Atlantic League early in 1909, and would have been ideal choices for a mid-season supplement to the regional cards already issued, most of which depict the stars of 1908."

First I believe the 48 Southern League players included in the set, as well as the 8 proof cards were selected in early 1909 prior to or just after the seasons starting for the Southern Association and South Atlantic League. Note Dwyer is depicted with Jacksonville and was traded to Columbia in early July.

Second concerning the "mid-season supplement", 34 of the 48 that did make the set were first issued in August and September of 1909 as the seasons were wrapping up. The additional 14 cards along with the other 34 were printed in the first run of the 350 series in very late 1909 or early 1910. As I have said these 14 were not a supplement to the first 34 printed but part of the 48 decided on in early 1909.
