At the time, there were a lot of characters with the name of Phantom and some kind of qualifier: Phantom Magician, Phantom Detective, Phantom Reporter, Phantom Fed, Phantom of the Fair/Fantoman, Phantom Bullet. Some like the Phantom Reporter were referred to as just the Phantom in-story. Admittedly, Bob predates 90% of them so his taking a first name is a bit odd. But, he's such an early entry into superherodom, how much of that might be just the fact that the bulk of characters AFTER him didn't? It seems odd to us looking back through the thousands of later characters. A lot of your non-masked action characters were often identified with a half-name/half nick-name monikers, possibly growing out of the Dime-Novel and early serial traditions of Buffalo Bill, Dead-Eye Dick, Spring-Heeled Jack, Burn 'Em Up Barnes as well as DC's Congo Bill and Slam Bradley. Even Doc Savage has that informal/formal pairing up though it's a title and his last name. From that side of the equation, maybe the name didn't seem as being an oddity. Had Bob Phantom come just a year or two later, maybe he'd have realized that it was pairing of colors with your name that was the inside track to success as a comic book superhero. Look out world here comes Green Bob! Maybe not.

What's also surprising is that he may not have been the first Bob Phantom! In doing research, I had come across a reference to another one, though I've not been able to verify the character at this time. Quoting from my site: According to a Ron Goulart piece on the history of MLJ (Comics Collector, Winter 1984), there was an even earlier Bob Phantom, a mustached magician (Shades of Mandrake!) that appeared in Harry "A" Chesler's Star Comics #1, 1937.
