A dream story rather than high fantasy
(See the parent record under the original title.)
WorldCat record OCLC 179272486 reports:
-- "[(c)1929]"; series "A Just Right book"
-- 233 pp, 8 color plates, 21 cm
-- "Cover Drawing by Alexander Key", probably from the book; that is, as credited
That record identifies the writer and interior illustrators by canonical name only (that is, the Responsibility field of record OCLC 179272486 is missing).
Sabin, Abbott, and Knipe are credited here as in the original 1910 ed. from G. W. Jacobs, thus also as WorldCat reports of the 1920 ed. from Whitman (that is, under two different titles; both reported as 233 pp).
Front cover credits the writer as Eldridge H. Sabin with a 'D', which is a mis-spelling found in some newspaper coverage of 1st eds. of his children's books. Title page of Archive.org copy credits the writer as Elbridge Sabin. Copyright page lists 7 "Other Titles $1.25 Each".
