At SXSW, I discovered a new designer, JESS3. I kept finding different creative designs posted all over Austin which made me want to find out more about the person behind such detail. I was able to track down the culprit via twitter and found that he too has a love for Sharpie! Above is a picture of a mural that @JESS3 tweeted me, which was made with black Sharpie markers.
