I am attaching a couple of what I think are my rarest pennants. The first is the '24 Washington pennant, very plain looking. It seems to be very close to that '25 Pittsburgh pennant I mentioned before, except that the latter pennant had a batter graphic inside the baseball. The second pennant is a minor league pennant of the Newark Indians from 1913, as I understand it they were sort of a minor league team for Brooklyn, owned by Ebbets. This shows some wear and is missing about 2" off the tip.
I am also including, for the heck of it, one of my favorite pennants (Astros), albeit not a very old one. I think this was a Keezer pennant although it does not have the stamp on the back.
I'll post some more in the days ahead. Thanks for your input guys,
Greg
