The House at Pooh Corner by A.A. Milne. A 1961 hardback by E.P. Dutton & Co. “Decorations” by Ernest H. Shepard; design credited to Warren Chappell. All three books this week come from a box my mother-in-law dropped off, containing maybe two dozen of her old books.
Heidi by Johanna Spyri. A 1945 Grosset & Dunlap Illustrated Junior Library hardback edition. Illustrations are by William Sharp, but no designer is credited for the hardback cover. My guess is that there was a dust jacket for this book at one point.
Spelling Goals (Three) by May Lambader, William Kottmeyer, and Rose Wickey. 1951, hardback, Webster. Illustrations by Edward Miller and cover by Christine Chisolm.
