Never mind this film is set in the 1950's, and neither of those models existed at that time. Better they should have gone with the Western Horse!
Thanks to Sarah R. for her sharp eyesight!
This blog springs forth from the age-old model horse hobby pastime of noting "Breyer Sightings"; instances where Breyer model horses (and other beasties) are used as props or set decoration in films, television shows, and even print ads. It's harmless fun, and intriguing as to the many places these treasured collectibles find themselves! Enjoy!
