"Certain Brief Conclusions from Selected Letters of Lambert Wood" is an 80 page, 6"x9.25" hardcover published in 1939 by Binfords & Mort (Portland, OR). It consists of letters written by Wood as he served in France with the American Expeditionary Force during the First World War. He fought at Chateau-Thierry and the recapture of Vaux, and died in combat two days after posting the final letter. His mother Elizabeth Lambert Wood, a popular Oregon-based author, issued the book as a memorial some two decades later. There's a tipped-in portrait of Lambert opposite the title page.
