I hope this link works ... I have twelve 1969 Mets pennants. There may be more. All of these are made of cloth. Top six are Trench, five are ASCO and the last (with the weird orange crown covering "Eastern Division") is that unknown NY company.
I think I may have seen a couple of knock-off types on stiff felt. If there are others on cloth, let me know ...

EDIT: I guess logically there must be at least one more, the last one without the crown ....
