I came across this ca. 1976 Philadelphia Eagles pennant, by ... Trench? ASCO? Not really sure.
I know we've discussed the mysterious "VET" mark before as a possible concessionaire's mark associated with Veteran's Stadium; but what about this one being marked, "NB"??
Maker's mark? Concessionaire's mark? Philadelphia-area sporting goods store?
if only we knew a pennant collector with knowledge of the Philadelphia sports scene in the mid-1970s....
