Local T-shirt purveyor Dirty Coast has partnered with the New Orleans Public Library for its nonprofit for 2015.

The group recently debuted the newly designed “New Orleans is Okay in My Book” T-shirt. The design is “a fun take on some of the classics written in or about our great city,” Dirty Coast creative director Blake Haney said. It is an example of how Dirty Coast “creates a unique line of T-shirts that proclaim local identity of New Orleans and are guaranteed to strike a conversation.

“We felt this was a natural collaboration. The New Orleans Public Library is such a champion for the rich history and bright progress of the city of New Orleans. This will be a great way to shine light on the wonderful work they are doing in and for New Orleans.”

Each month throughout the year, Dirty Coast will donate 20 percent of all sales in-store and online on the 20th of each month.

“We are very excited that Dirty Coast has selected the New Orleans Public Library as their 20-on-20 partner for 2015,” said Charles Brown, executive director and city librarian with the New Orleans Public Library. “This partnership is such a fun way for the library to receive some much-needed financial support and to gain some much-needed awareness of all of the great things our 14 locations have to offer.”

The T-shirts are available at www.dirtycoast.com or at the company’s locations: 5631 Magazine St., (504) 324-3745; or 329 Julia St., (504) 324-6459.
