OilFieldHockey.com says "a trademark search this morning has uncovered the Logos for the Oklahoma City Barons." They then call it "official" — which it isn't, by the way, until an announcement is made by the franchise.
That being said, they do appear to be legitimate logos, and the images are hosted on the USPTO servers.
OilFieldHockey.com claims credit for finding the primary and word marks (top and bottom) while crediting The Copper & Blue with the OKC secondary mark (middle).
And for what it's worth, the @OKC_Barons Twitter account I talked about yesterday is now decked out in the new logos. It doesn't make any of this official. But if it's not, it's a really good ruse. I'd expect the official announcement in the next few weeks.
Start the countdown! Prodigal Hockey, which operates the new Oilers-affiliated AHL team has just announced that the team's name, logo, colors and uniforms will be officially unveiled at a press conference on Wed., May 19. The event will take place at 4 p.m. at the Cox Convention Center in Oklahoma City.
