Signature Books are a series produced under the general editorship of Enid Lamonte Meadowcroft, and published during the 1950s and 60s by Grosset & Dunlap. This series provides easy to read, exciting, and factual stories based upon the lives of historical figures. Though written simply enough for young readers, they make interesting reading for teens, too.
Enjoyable even if this was written for much younger readers than myself. I found a quick read while still being interesting and learning some things I either had forgotten when I was in school, or never learned.
