Then there are portraits of the dodo, griffin, unicorn and horror portraits of ogres and orcs and such like for those who dislike "cute" wildlife works. And all are agreed there is nothing cute about an ogre or an orc and those galleries that focus on the darker side of art have a wide audience (not just from the ogre and orc communities either).
Books are written on all aspects of Kingdom flora and fauna, mostly by Fresdian, and these have become classic reference works. The Queen occasionally arranges for a book of photographic portraits to be published and these always go down well.
