I'm assuming you are referring to the one with the Scissor-tailed Fly-catcher on it. I looked it up and found this story. Two comments, one frightening and one humorous are in that story.
"Every Oklahoma motorist will have to pay an extra $5 for the new license plate.
State officials say that money will go into a newly created public safety fund for the state and lawmakers will be in charge of that fund."
The humorous one:
"You don't have to get a new plate right away; instead, when your current one expires, go to a tag agent, pay the renewal fee and they'll give you the bird."
It's a copy of that thing over I-40, near the boat house dist, and that's suppose to be a flycatcher. Have a feeling Fallins addled starving artist daughter designed both.
