Several pieces of artwork critical of presidential candidate Hillary Clinton have appeared around Los Angeles and Beverly Hills ahead of a trio of pricey fundraisers the candidate will attend this week.

Fake, tree-shaped car fresheners with an image of Clinton in the middle have been placed at the corners of Sunset and Amalfi, Sunset and Capri and Sunset and Allenby in the Tony Riviera section of Pacific Palisades, home to Hollywood luminaries like Ben Affleck, J.J. Abrams, Steven Spielberg, and Tom Hanks.

The air freshener’s caption? “Stench of Corruption.”

Clinton is set to attend three high-priced fundraisers on Thursday, May 7. In the morning, Clinton will appear at the Westwood home of Women’s Political Committee member Catherine Unger for a $2,700 per plate women’s breakfast fundraiser, according to the Hollywood Reporter.

In the afternoon, Clinton will attend a $2,700 per plate fundraiser luncheon at the Pacific Palisades home of legendary television producer Steven Bochco and his wife Dayna. Sen. Barbara Boxer (D-CA) is reportedly set to attend the fundraiser as a special guest.

Later Thursday, Clinton will head to Beverly Hills for an early-evening $2,700 per plate fundraiser at the home of billionaire entertainment mogul Haim Saban and his wife Cheryl. Saban has been a longtime friend of Clinton, and has donated more than $10 million to the Clinton Foundation and Bill Clinton’s presidential library. Sports agency magnate Casey Wasserman will co-host the event at Saban’s home.

The artwork appears to be a reference to Clinton’s messy corruption scandal, first exposed by Breitbart Senior Editor-at-Large Peter Schweizer in his book Clinton Cash: The Untold Story of How and Why Foreign Governments and Businesses Helped Make Bill and Hillary Rich.

So far, it is unclear who was responsible for putting up the fake air fresheners, however one well-known artist has already plastered anti-Hillary artwork around town this week.

Sabo, a guerilla street artist who has poked fun at Clinton in the past, put up mocking posters of the candidate in Bel Air, Holmby Hills and Pacific Palisades earlier this week. One poster, a parody of the animated film Shrek, calls Clinton “Shrew, a Jeffery Katzenberg Creation,” and another, a parody of the HBO hit Game of Thrones, reads, “All Men Must Die.”

Of course, anti-Hillary street art is nothing new; just last month, an unknown artist posted signs all around Brooklyn that lampooned Clinton supporters for claiming certain words used to describe her were sexist.
