Class is usually a more subtle dimension of ads than race or gender.  I think, and I admit I am speculating here, that it is because there is a need to, usually, appeal to the masses while at the same time suggesting that the masses do or should have access to the most high-class things (which they do not).  Thus, the difference between being middle-class and upper-class is minimized at the same time that the symbolic attainment (only) of upper-class-ness is being sold to middle-class people.  There are exceptions, of course, such as when ads aimed at the upper-class sell product by suggesting that a middle-class person could never afford it.

Anyway, these ads, found here, are from 1962 and 1963. I thought they were interesting because of the way they communicated wealth and luxury, mostly with location.

Notice the very old giant trees, ivy-covered ancient-looking stone, an archway, and hedges… all in what looks like a private residence.  The copy, which suggests that I’m right about “symbolic attainment,” begins:

How much does a Cadillac cost?  Take a guess–and then check with your authorized Cadillac dealer.  Odds are you’ll have guessed too high–for a Cadillac can be remarkably modest in cost.

There is a beautiful woman in the expensive-looking dress, of course, but also notice the cobble-stone circular driveway under her feet:

The chauffer communicates a certain degree of wealth, of course, but also the stone driveway decorated with greenery:

Cobblestones, again, and a very expensive New York City apartment building.  Copy includes the following comment:

“…the new 1983 car is the most rewarding possession a man can have.”
