Colorful covers distinguish this series of western mystery stories written in the early 1960's by Troy Nesbit. This cover has come away from the spine in a few places, but could be easily glued back if one chose. Otherwise it is very clean, with no marks, tears or stians to the pages. End pages are the green plaid ones from Whitman publishing. Illustrated by John Walter. No marks, tears or stains, just age discoloration of the paper.
