Just trying to track down the info on the photo for fun.
" The original Trigger, named Golden Cloud, was born in San Diego, California. Though often mistaken for a Tennessee Walking Horse, his sire was a Thoroughbred and his dam a grade (unregistered) mare that, like Trigger, was a palomino. Movie director William Witney, who directed Roy and Trigger in many of their movies, claimed a slightly different lineage, that his sire was a “registered” palomino stallion (though no known palomino registry existed at the time of Trigger’s birth) and his dam was by a Thoroughbred and out of a “cold-blood” mare.[1] Horses other than Golden Cloud also portrayed “Trigger” over the years, none of which was related to Golden Cloud; the two most prominent were palominos known as “Little Trigger” and “Trigger Jr.” (a Tennessee Walking Horse listed as “Allen’s Gold Zephyr” in the Tennessee Walking Horse registry).[2] Though Trigger remained a stallion his entire life, he was never bred and has no descendants. Rogers used “Trigger Jr.”/“Allen’s Golden Zephyr”, though, at stud for many years, and the horse named “Triggerson” that actor Val Kilmer led on stage as a tribute to Rogers and his cowboy peers during the Academy Awards show in March 1999 was reportedly a grandson of Trigger Jr.[3]
