Yard decoration

This was a car stopper. Seeing this concrete column with a sculpture of a horse trying to squeeze its way out, had me braking to a stop in order to take a closer look. I immediately saw it was not alone. There were possible a dozen other columns, all with realistic sculptures poking out.

These were clearly lawn ornaments -- somewhat sophisticated lawn ornaments. These were not the usual garden gnomes with pointed hats. One column I could understand. A couple, one on each side of the driveway might work. But a dozen scattered about the yard seemed a little much. Was this a display of items for sale? If it was, was this legal in a residential neighbourhood?
