After some further checking on the BF2 pennants I have......

They are supposedly original to the product from my understanding, and you occasionally come across B18 pennants with a stamp still attached on the back. I have three with a back stamp myself. They are somewhat rare, but not necessarily worth a large (or any) premium in my experience.

However, the stamps I have on the backs of my BF2's are different than your stamp. Your stamps are more square, white, with all black and red print. My stamps are more like a thin strip, with a tan/off-white color material, and that start with a larger designated number on the left of the stamp, and then on the right side of the stamp, three lines of some much smaller print. My large numbers are presented as: No. 679, No, 18, and No. 307. Oddly, the first two are printed in black ink, but the third one is in a light green color. And then to the right of all three of these numbers, there is a further, though much smaller, three line printing that is done in red ink. These smaller printings are all similar in nature and content. They show as follows:

Board
5283
GJJ

These are exactly the same on the two stamps that also have the larger numbers to the left printed in black ink (Nos. 18 and 607). They are also both Guy Morton BF2 pennants, which may explain the similar 5283 numbers on the stamps. But then why the two different larger numbers on the right side of these Guy Morton stamps (No. 18 and No. 607)? The additional printing on my Joe Judge BF2 pennant stamp with the larger green number, No. 307, reads with a different number printed under the word "Board", as follows:

Board
5247
GJJ

Am not so sure now what the difference is between the two different types of stamps on these. Nor exactly what the larger numbers refer to, or the differing numbers written under the word "Board", that seem to go along based on the color of the print of the larger numbers on these stamps and/or the player on the BF2 pennants. Also, no idea what the GJJ on all three stamps stands for either.

So now I have even more questions as well, and wonder why the back stamp on your BF2 pennant differs from the three back stamps on mine.

Out of curiosity, who is the player on the front of your back stamped pennant? Oops, see you already posted it is Buck Weaver on the front.
