I can't recall seeing this ad before! Wonder why they're showing a sea plane (probably not the technical term for it but it's on water). Is smoking in such a plane safer? o_O Or were they trying to get more people on those planes and that was an incentive? The mind boggles at what advertisers were thinking at times!
Yeah, it's very weird.

I can only think it must have been very early on in the industry and t hey were just trying lots of weird stuff to see what would connect with the public.

It could also have been a regional ad of some sort.
