Porcelain Fish Mystery by Harriette R. Campbell
Advance reading copy (but not an uncorrected proof) of the first edition. All are the sewn signatures bound in plain wrappers, with the dust jacket pasted to the covers and the flaps removed. Laid in is a red 3x5 card with the publication info hand-typed on it. It is dated March 25 1937, with a publication date of April 26th. It states that her first book "had a sale of 3,000 copies."
