Rare 1998 Undated Masters Tournament Flag

This is from 1998.  For collectors you can tell its pre 1999 and not the same undated flags that the club sells the members or past champions.  The material is heavier and stitching is thicker from post 1998 flags.  Additionally,  you can tell the difference between Undated Pre-1999 and Post-1999 Masters flags by gap in the shadow stitching under California / Arizona. For comparison I have a pics 6-8 where you can compare.   The flag is absolutely mint and has been in storage in a smoke free home since 1999.  Most collectors agree that the 1997 Masters flag is the rarest and most valuable.  A close second is the 1998 undated flag which is being offered today in true mint form.
