Halloween // Looking for NFFA (Purge series) flag

Hi everyone. I'm trying to hunt down an NFFA flag from the Purge series. I'm planning on doing a Purge theme for my outdoor Halloween decor this year and I think the flag would be a great piece to add to the display. But I'm having zero luck finding one. Anyone have any leads on where to get one? Or any other Purge decor, for that matter?
