While the American Paint Horse Association (APHA) is headquartered in Fort Worth, I could not find any specific information about a separate "American Paint Horse Heritage Foundation Inc." in the city.
To find out more, I suggest you try the following:
* Contact the APHA directly: They may have information about a heritage foundation or a related organization.
* Search online for "American Paint Horse Heritage Foundation Fort Worth": This may lead you to a website or contact information.
* Check local historical societies or museums in Fort Worth: They may have information about the history of Paint horses in the area.
I hope this helps!
