Above, the covers for George Maxwell’s Tirez à vue! and Colt en main!, aka Shoot on Sight and Colt in Hand. Maxwell is a bit of a mystery. He was born Edmond Georges Marius Esposito, wrote as Maxwell, Erynx Applegate, and perhaps other pseudonyms. These books were published by Éditions le Pont Neuf’s for their Miss Luger Collection, 1958, a series consisting only of these two entries, actually. Cover art is by unknown. These French pulp writers and artists… always so impénétrable.
Lady with a Luger (and later a Colt).
