It's your obligatory "kids on a horse" photo!
Every child of the 70s or 80s has one of these. I don't know why, but I think it is a rule of the universe or something. Parents were required during those decades to sit their children on a horse-like creature or object and take a picture. There were entire industries built around the taking of children's photos upon horses (in Tijuana, Mexico, for example, or so I've heard)
In younger generations it is hit-or-miss whether a given family will have provided their children with this important life passage.
