A couple of interesting items of note. First, no one in this issue (or the next, as I'm told) references the fact that Lobo is a person of color. He's just written as any other character might be. Second, Arneson is surprisingly judicious with his dialogue; there are a number of panels that are completely wordless. A testement to both Tallarico's storytelling ability, and Arneson's restraint.
Evidently, later on, Arneson and Tallarico couldn't agree on how exactly the character and/or book came together originally, but it would be more than a few years before another Black character headlined his own title. Arneson claimed sales were the only reason for the book's discontinuation, but I'm a little skeptical of that. There were ten months between the first and second issues. Plenty of time for sales of #1 to come in. Why produce a second book if sales were that bad?
