I just discovered the desnudatón university student protest on this page from 2013: (forum.oneclickchicks.com/showthread.php?t=21825&page=49). There are several nice posts, including a video posted by crispus. I must say, this is one of the hottest girls I've ever seen go nude in public, in my opinion. I found some higher resolution images of posts from that page, plus some that aren't on that page. I apologize if these were already posted, but when I searched desnudatón, nothing else came up.
Here are some full frontal high res images from Getty:

There are a couple of nice small images of her at the end, though the front is censored:

(A reverse image search of the first image below reveals that a slightly larger version could exist.) I would love to see more footage of this decade old protest! We can only hope!
Cheers!
