Somehow, this ad seems analogous to the extraordinarily mild, globally-warmed winter we've had this year; to really make that point, I'd insert a comma between the two words of the headline.

The photojournalistic approach to the subject is such a departure from the happy-family-in-full-color-clamoring-at-the-maw-of-the-overstuffed-fridge school of advertising that was typical of selling appliances in 1968. Indeed, it aspires to emit a bit of the brash charisma that characterized that year's heavyweight boxing champ, Muhammad Ali.
