A mysterious artist is posting cartoons attacking Goldman Sachs and Hillary Clinton around New York City

A street artist has set their sights Goldman Sachs and is putting up stickers around New York City attacking the investment giant.

Business Insider has seen two of the stickers, which both feature a version of the company's logo modified to say "Goldman Rats" and an image of a cartoonish rodent sticking out its tongue.

One of the stickers (pictured above) is captioned "PHOOEY ON YOU, POORS." I spotted it in the subway last week, but it seems to have been around much longer. A Pinterest user based in New York took a picture of the same sticker about one year ago.

The second sticker also includes a shot at Democratic presidential candidate Hillary Clinton. Text surrounding a picture of the cartoon rat declares, "WE'VE SELECTED HILLARY FOR YOU SUBMIT, POORS."

I spotted the Clinton sticker in a Brooklyn subway station last week, but it seems to have appeared in multiple locations. A blog dedicated to Brooklyn street art posted a picture taken of one of the stickers last month.

The Clinton sticker is clearly relatively new. In the sticker, the "H" in "Hillary" is copied from her campaign logo, which was unveiled when she launched her campaign in April. It echoes a line of attack that has been used by one of Clinton's Democratic rivals, former Maryland Gov. Martin O'Malley (D), who has suggested Goldman Sachs would like to see her in the White House.

It's not clear who made the stickers..

The "Phooey" sticker bears a graffiti signature, but I can't make out what it says. If you know more please get in touch.
