Export Feder Tag Repro?

My '71 Demon exported brand new from Hamtamck to Belgium in May, 1971 doesn't have these kind of metallic tag under the hood, but an export blue sticker on the driver door jamb :

International sale "I" code on the fender tag :

So, I suppose that the export metallic tag did exist only during the '60s and not during the '70s
My two cents...
