Very few talented engravers have the luxury of studying exotic animals and birds in the wild in order to duplicate their features in steel and precious metals. Most work from stuffers or photographs. Even stuffers can give off incorrect images, so, I assume most engravers do their best and most accurate work from good photographs. That is the situation with Ken Hurst. I have watched him work, and he does not claim to travel to Africa to study for his next commission to engrave an African animal. He sits a photograph or other good image next to his vise. Oddly, the image in steel is a wonderful rendering of the photographic image. End of story, except to say that "I like the pig."
