Most folks know that six flags have flown over Texas.
That's just the tip of the iceberg, pardner.
Over at Texas A&M (Farmers Fight!), Wallace L. McKeehan has a fabulous rundown of the lesser known banners throughout Texas history.
DeWitt Colony Flags 1700-1836
Flags of Independence 1835-1836
I guess it used to be easier to figure out which way to fly the flag when it had words printed on it.
