The fact that San Francisco artists Francisco Aquino, Mona Caron, Susan Kelk Cervantes, Jetro Martinez, Sirron Norris, Henry Sultan, Jennifer Badger Sultan and Martin Travers had images of their artwork yanked from sfmuralarts.com, a website that displays local public art online, was bad enough. But then they found out that their art was being used by Zephyr Real Estate to sell luxury condos in the city. So they sued.

From San Francisco Weekly:

Eight muralists on Tuesday submitted a federal complaint in San Francisco against Zephyr Real Estate, the city’s largest independent real estate firm, for allegedly using unauthorized reproductions of copyrighted works of art in a 2013 calendar to advertise properties.

"We tried before filing a lawsuit to resolve matters with Zephyr and that was frustrating," said attorney Brooke Oliver, who represents the plaintiffs. "The artists regret having to file a lawsuit but are determined to protect their rights to not have their artwork taken without their permission to promote a real estate company that is so deeply involved in gentrifying the San Francisco neighborhoods where these murals live."

A representative for the company told the SF Weekly the accusation that company used the calendars for profit was "completely wrong."
