Many thanks to @FadedYouthBlog for tweeting their link!
Faded Youth Blog has posted 16 photos of Keanu Reeves’ stop at a grocery shop yesterday in Punta del Este. There are 16 decent sized photos. Of the 16, at least 7 are new.
The photos are here.
Also thumbnails of the entire set is at REX. Between the photos posted by the Mail Online and the Faded Youth Blog, a fair number of the photos are available.
I counted up over 70 photos that are currently available.
Update: There are additional photos here and here.
Update X2: Zimbio has posted a set of 27 photos. They are at 300 px and enlarge to 1200 px and maintain their quality.
