I got this lovely Royal Krona beetle with a "Royal Krona Sweden" label, and another label with "Form Lisa Larsson" on it. I know from this post: http://www.glassmessages.com/index.php/topic,3258.0.html
that Royal Krona functioned from 1974 to 1977, so I do know when (more or less) my beetle was made.
Now for my question... Right above the labels, etched into the glass is 'Nike 80'. Can someone tell me what this refers to? I've tried googling it, but all I get are results from the sporting goods company.
