A "cool caveat" if there ever was one, the "Warning" card is reminiscent of the days of Blades and Mumbos. Using the word "Warning" even seems to have been a prelude to Oakley's "quasi-military image" days which followed a few years later. Perhaps best of all, the card not only "warned" the consumer about the possibility of iridium being scratched, but it also bragged about the lenses themselves.
