Out of print.
From the publisher:
Edited and designed by Eisner Award-winner Dean Mullaney, the strips are reproduced from pristine syndicate proofs that will allow readers to see, for the first time, the full luxurious detail of Raymond's brushwork. Includes a biographical and historic essay by Brian Walker, and an introduction by Raymond biographer and authority Tom Roberts"
While I beg to differ on the quality of the reproduction (two foreign language editions offer superior line quality), this collection does have the best reproduction of any previous American edition and almost three years worth of strips.
