I want a 60's wheel cover in photo

I am not sure what year or style of car it came off of, but I am looking for one of these in driver shape. I only have three right now. What is is originally from? I hope the pic loads. Thanks all.

Title should say, "I want a 60's wheel cover in photo". Sorry, I was too tired when I posted.

Looks like it is a 67 or 68 plymouth. I don't know, but I like it and want one more to complete the set on my car.
