The Sports Illustrated Swimsuit Issue has been a beloved annual tradition since its debut way back in 1964. That means the upcoming 2014 issue will be the 50th, but there’s an easy way for you to catch up on the five decades worth of covers before the latest one comes out next month, thanks to this animated GIF from SportsHumor (check them out here).
That’s 49 Sports Illustrated Swimsuit Issue covers in less than a minute. You go from Babette March to Kate Upton, with all of the evolving swimsuit styles and models in between. I’d recommend propping your eyelids open (Clockwork Orange-style) and really soaking them all into your brain.
To do that (or just to give it a look in a more traditional fashion), take a look at almost 50 years of the Sports Illustrated Swimsuit Issue in the animated GIF below. And watch for the latest installment soon, since it traditionally comes out sometime in February.
