Every cover of Esquire Magazine from 1933 to the most current issue.

The first several years have weird claymation looking type figures as illustrations on the covers. Reminds me of the 1960's classic Rudolph the Red-Nosed Reindeer and that other one that had the Heat Meiser in it.

According to the site these are:

The Esky Years
These are the year's when Esquire's cover was dominated by our mascot, Esky, a mischievous little man whose interests ranged from mountain-climbing to soldiering to — on one special occasion — trying to climb into Elizabeth Taylor's cleavage.

Weird. But still —overall it's an interesting collection that chronicles time through design trends and style. There's even an aalphabetical subject index to peruse if you don't feel like trudging through 70 years of covers.
