The illustrated artistic representations of animals in the slides that I’ve been cataloguing have shown both an artistic romanticization and an attempted realistic depiction. Additionally, in pre-photography days it was important for breeders and scientists to have artists depict the high quality animals to show the traits of the best of the breed. It’s been interesting to see how the physicality of the animal compares between an illustration from the 19th century and a photograph from the 20th century. http://www.societyofanimalartists.com/
