I agree, it's a fabulous -- museum worthy -- collection of lighters!!
Really amazing set.

As smoking slowly fades from its post-war apogee, these will become increasingly rare. An ensemble of smoking-related casino logo'd collectibles -- these lighters, plus logo'd ashtrays and matchbooks -- make an interesting sub-group.

Or more broadly, a grouping of casino-related "vices" items -- chips of course, plus items such as logo'd liquor decanters, barware, swizzle sticks, bar napkins, etc. -- rounds out examples of an earlier time when Las Vegas was synonymous with "Sin City" and Nevada was that naughty state out West where anything goes!
