Yup, John Wayne was definitely a very heavy smoker and made several (TV) commercials, magazine ads, billboards, etc - promoting cigarettes - as did a great many other Movie Stars and Celebrities of his time. Today of course, smoking and tobacco products have fallen into disfavor and any such advertising is now banned.
Despite this, there is still some subtle forms of smoking advertising and promotions that still have a viable market - and which capitalize on John's enduring Iconic Star Power. One such product is cigarette lighters. Zippo lighters almost seem to have an small industry using John's image.
Smoking still obviously has a certain 'manly' appeal to some people and many such John Wayne lighters are hot "Collectibles". Frankly, it's evident that ANY John Wayne endorsed product/merchandise will eventually - or immediately - achieve Collector and Memorabilia status.
Plenty more lighters than I show here ...
And finally ... if you really need to cut down
on your smoking ...
... the John Wayne knife lighter.
