"Call Him...Cottonmouth!" Part 1 of 2. Script by Len Wein, pencils by George Tuska, inks by Vince Colletta. Luke Cage arrives at the office of Hero for Hire to find a package waiting for him. When he opens it, deadly serpents spring out. Luckily for our hero, their fangs can't penetrate his diamond-hard skin. This little gift was a calling card of the new player in town. A man who is every bit as strong as Power Man and probably deadlier, the gangster known as Cottonmouth. Letter to the editor from Michael Gilbert (the comics artist?). The letters page also includes Marvel Value Stamp series A # 64 (Sif by Jack Kirby)
