Original vintage media trade magazine ad for SUCCESSFUL FARMING Magazine.  Horses into Ham and Eggs!  A noble animal but a poor power plant, the horse needs eight acres of land for his food.  The increase in tractors since 1920 not only gave American farmers more power to work the land but 55 million more acres once needed to support horses.  Art by (Van??) Schreiber. Old 1947 magazine advertising industry advertisement, would display beautifully matted and framed.
