This is what a 36ft Sharpie Mural looks like: The mural took redditor StretchyMonad 7(ish) months of coming into the gallery once or twice a week for 5+ hours. You can see it at the Los Angeles Contemporary Exhibitions (LACE) in Hollywood. If you come by this Sunday afternoon, they will be having an opening reception and StretchyMonad is pretty sure there will be booze. If he is saying there is a chance, I might just have to go.
