School me on "Vintage" and Dated Cigars

HI all....another noob question for you. I've noticed a lot of cigars labeled "Vintage" and also a lot of dated stogies, and even some of both...such as "Vintage 1993" or Vintage 1968 even.... sooo Whisky Tango Foxtrot...were these cigars made in 1968? or was 1968 tobacco used in their making? or is this just a name only kind of thing?? Thanks in advance...
