From the inside of a Nat Sherman box:

The year 1930 was the height of a Golden Age. It was also the year Nat Sherman began making luxurious cigarettes for his demanding clientele. Three generations later, our family persists in crafting cigarettes of only 100% pure and natural tobacco --- without chemicals or additives of any kind. We know from long experience it's the only way of making the richest, most satisfying smoke in the world.

I could kill for a pack of MCD Lights right now.
