These aren't necessarily on the walls along Katipunan avenue, but a set of street art found in the vicinity of UP Diliman's Shopping Center. So it's still technically "UP Campus Graffiti."
PROS: A work by my favorite artist collective ever, Gerilya? YES, PLEASE! These people mostly hail from UP FA but you could see their work even outside campus. I saw them first on this old overpass on Philcoa. Sadly, the bridge was already demolished, along with their Andres Bonifacio street mural. My all-time favorite would be their print, Balasang Boombox. Check them out on Tumblr; The other set in front of Shopping Center has been a canvas for different graffiti pieces. It first had "You either win or you learn," which was then painted over with "You either win or you die," and then finally with "You either win in the revolution or die in submission." As of today, there is a different set of street art painted on those yero walls - colorful sea creatures and beautiful maidens. I hope I could find out who the artist/s is/are soon.
CONS: Some naysayers say that graffiti is vandalism - it damages private/public property. I, however, have a different point of view. Street art is different from vandalism. When people destroy properties - like burning portions of walls or breaking glasses or painting messages of hate - then that's vandalism. Graffiti such as these, on the other hand, have aesthetics attached to them. Art evokes feelings and reactions, and if paintings on the street do, then they are art. Yes, even if they're just gang signs and names. Ever heard of Banksy? He writes his name on walls too, but it is art. Like auction-selling art. This is the type of art that is accessible and non-elitist, and I wish Manila would have more street art, especially those that are socially relevant and thought-provoking.
TL;DR: I simply love how UP is home to wonderful street art. read more
