Another difference is that the new subway graffiti usually looks like a crude scrawl, rather than the detailed writing or representational art that was common in the graffiti of years past and has shown up again on the sides of buildings from Williamsburg to the South Bronx.
that’s just making a relatively baseless distinction. yeah the graffiti of days past was more colorful, but that’s because they were using paint or markers. in the pic in this article, the new etched tags don’t look substantially different to tags in marker or paint.
