The above link will take you to the site for "The Yorkshire Terrier Magazine", which is a great magazine. It has tons of pictures from show breeders and will help you to maybe know more about the lines and the breeders. It also offers alot of educational reading as well. Lorraine Hayes from Pastoral places pictures of her up and coming champions along with her champions in the magazine quite often! I received the magazine 4-5 years before I ever became a part of breeding and showing.
