I found this gem at a library sale this past weekend. Copyright date is 1942, so The Little Red Lighthouse was probably first published then, though this is a softcover. This book is about the building of a bridge across the Hudson River into New York, it parallels the life of a lighthouse who thinks it will no longer be needed. Lynd Ward's illustrations are fantastic. Love the color palette. I'm short on time today, so I will not be doing a bio on Lynd Ward, but will save it for another time when I can do him justice.
