It was originally developed in England and was a beige coloured rabbit called... THE BEIGE Rabbit!
But this fellow Herbert Nielsson in Sweden decided to recreate it, and in doing so changed it's named to the Isabella.
Coming in at 6.6-8.8 lbs this medium sized rabbit with erect ears has a coat that is a yellowish-brown colour that looks coated with a blue veil. It has blue tips on the ends of it's fur. A mask on it's face, when viewed from the front, is oval-shaped.
You can see a picture of this rabbit.
