Dogs And How To Know Them Edward C. Ash, M.R.A.C. (Dip.). F.R.M.S., etc., The Epworth Press, London, GB, 1925 (1st edition)

On page 66 of this 88-page booklet there is only a six-liner about the Shetland Sheepdog, but on page 67 there is a very successful black and white drawing of the first blue CC winner Peat (Grey's), *30.1.1916, KCSB 1205 W (Clifford Sharper x Braeheads Rena), breeder: Mr. Walter Barnard, a blue, tan & white male, who is described as uniformly blue (among other things: "a blue without being a merle"¹, "He was not a blue merle, but a solid-coloured blue or grey dog."²).
Very interesting is also the reference list at the end of the book, which lists all published dog books from 1800 to 1925.
