My Father's Dragon

First-printing test on the copyright page: the 1948 date with the note of simultaneous publication in the United States and Canada, no statement of any later printing, and no Library of Congress number or ISBN. Jacket point: the first-issue jacket makes no mention of the Newbery Honor, which the book won in 1949 — later printings and reprint jackets advertise it, so a jacket touting the Honor is not a first (Burnside Rare Books, ABAA, corroborated by other dealer collations)
