This is a set of 3 US Mag center caps I saw on eBay in 1999. I lost the bid, but have never seen another set since. They have a cool engine-turned background and a transparent red, white, and blue graphic over them. I thought they were cool then, and I just found this pic, and I still think they are cool now.
I’ve been down that road before, even did a V8TV segment on it 10 years ago. The trick is getting silk-screen looking print on engine-turned film… it’s not as easy as it sounds! I spoke with a bunch of graphics shops, none can seem to pull it off.
