Graffiti became an integral part of hip-hop culture

The visual art form began taking off in New York alongside the music of hip-hop. Both were postmodern forms of art that repurposed preexisting materials. For graffiti, that was by using the city as canvas. For rap, that was through sampling. This retrospective not only shows how the two forms intersected, but also how the public perception of both changed over time.

Graffiti is more than just tagging a name. Legendary street artist Carlos Mare, also known as Mare 139, breaks down how to paint several of the form's popular styles and motifs, from quickly drawn throwies to intricately planned masterpieces.

One baker is likely responsible for several of New York's earliest pizzerias

In 2018, a graffiti artist sued HBO for including their work in one of the network's shows

‘Mint marks’ are tiny letters on US coins that correspond to which mint location created them

As more mint branches opened up after Philadelphia (the first mint location), these “mint marks” helped hold each branch responsible for the quality of the coin.

How a polluted New York City waterway created extremophiles hungry for 'black mayonnaise'

In the 19th century, coal processing plants, oil refineries, a tannery, and other industries lining the Gowanus Canal contaminated its waters with coal tar, sewage, and other pollutants, forming the toxic sludge.
