Here are just a few notes that I have regarding the different Cobb "rookie cards." For reference, the World Series that year started on October 8 in Chicago and ended on October 12 in Detroit.
Detroit Seamless Postcard - of the six known examples, five are postmarked - three on October 4, 1907, one October 5 and one on October 7.
Wolverine Postcard - the earliest postmark from this set that I can find is October 9, 1907. Few of the postcards from this set found cancelled.
AC Dietsche - the earliest postmark from this set that I can find is October 9, 1907. Only a small percentage of postcards from this set are found cancelled.
HM Taylor Postcard - the earliest postmark from this set that I can find is October 7, 1907. Most of the postcards that I see from this set are canceled..
W600 - first offered to the public in the October 19, 1907 issue of the Sporting Life.
