Design scout Aaron Cohen's finds have been on Daddy Types before, but this 1960s molded plastic rocking horse rattle by Antonio Vitali is the first I've seen anywhere. It's from Otto Maier Ravensburg, the German board game company that went on to become a top puzzle manufacturer. [Ravensburger also bought the floundering Swedish toy company BRIO last year, but that's another story.]
Anyway, for the moment, the horse is available, so jump on it.
