From the publisher:

In the third volume--reprinting every strip from 1951 and 1952--new and old characters are paired off. Breck Nazaire and Dr. Deen Wilderness return. Steve meets the lovely Duchess of Denver and the sadistic Fungo; gets assigned to Eel Island, where he encounters crusty Colonel Index and his not-so-blushing bride; is sent to protect a government secret at Maumee University, only to reconnect with Summer Olson and meet her mysterious friend, Kate Subjekt; and eventually gets caught in the deep woods with Miss Mizzou and Roy Himmerskorn before coming face to face yet again with not only Summer, but the Copperhead herself-Copper Calhoon!

Steve Canyon like you've never seen it before -- reproduced directly from Milton Caniff's personal set of syndicate proofs!
