Customs Anyone know what this wheelcover came off?

A guy sent me this picture, asking if I could identify this wheel over. I’m leaving it up to the experts here! I have no idea...

 

Well, it's an Oldsmobile cap, possibly 57 or 58. 14" or 15"?

Enjenjo wins, 58 Olds 88 14 inch caps but they make only fit 57 Olds wheels or wheels that are quite similar. The cap sets into the wheel quite a bit and don't pop on all wheels. Dad had a 57 Super 88 but I am not sure it had those caps.

Example here.
