I imagine that by 1946 there were probably dozens of Will Eisner's "The Spirit" copycat comics on the new stands, and every time there's a huge success in the media, inevitably it will be followed by some rip-offs.
And I also know that sometimes some of these rip-offs even have quality points in them, and can be quite entertaining.
This is obviously not the case with The Barker.
Similar in concept, in costume and general thematics with Eisner's The Spirit, it is not, however, similar in quality.
The first story lacks in humour, suspense and is quite boring. The plot couldn't be more predictable. The art is average in my opinion (but fails disgracefully when compared to Will Eisner's).
Even the main mystery of the story is not solved by the protagonist himself !!
It is indeed solved and revealed by "Midge", the sidekick (who is a caucasian version of The Spirit's sidekick "Ebony White"). He's the one who discovers everything and reveals to Carnie Calahan.
Barker is described in the first page as "spieling" and "genial".
Well, in my point of view, he (at least in the first story) was nothing more than a spectator, because all the credit belongs to Midge.
The cover states proudly "The Barker in a Carnival of Laughs and Thrills"
Barker is there, The carnival is also there
