-Comment: I think this is the famous Mexican boy actor Cesáreo Quezadas ‘Pulgarcito’ in jeans and a Cowboy hat. I think role swap with a girl. Uncredited character names. Title means Boy or girl?
I found it by coincidence and only checked it briefly. Pulgarcito also starred in Santa Claus (1959), rating 2.
There’s also a real girl in pigtails, also riding (soon on my pigtails blog, rating 4).
