A few weeks after Michael Brown's death rocked residents in and around Ferguson, Missouri, a small printshop in St. Louis took action. The graphic design studio, dubbed Firecracker Press , began hand printing posters emblazoned with the words "Promote peace in St. Louis ."

Amidst protests and heightened police presence in the city, the posters were made available to customers free of charge. Not surprisingly, the shop "sold out" of the wood type creations, though the print continues to live on in photos across sites like Twitter and Instagram. "Tell the world you support the debate thats happening in Ferguson, MO and in the St. Louis region," Firecracker wrote on its website. "Issues of inequality touch everyone some more than others. Making posters is our small way of sharing our voice."

Firecracker began offering its "Peace Posters" online, charging only for shipping and handling. "FedEx got its cut," Firecracker owner Eric Woods explained. "But we didn't make a penny off the posters. Some people wanted to donate money. And that money went to our nonprofit, Central Print." (Images courtesy of Firecracker Press)

Firecracker owner Eric Woods , the mind behind the design, is one among many artists who spoke out after the shooting of an unarmed 18-year-old three months ago. From street art to paintings, murals to illustration, artists have been quick to echo the nation's near constant calls for justice and clarity in the wake of Brown's killing. The landscape of West Florissant might be marred by isolated acts of vandalism and law enforcement crackdowns, but art is still flourishing.

"I was so upset seeing Michael Brown's mother on TV... that I felt I had to do something to express my grief and anger at the way the police handled the situation," painter Mary Engelbreit recalled to HuffPost over email. Her illustration, "In the USA," made headlines in August . The image depicts a black mother and her young son sitting over a newspaper headline that reads "Hands Up! Don't Shoot." Above the cartoon are the words: "No One Should Have To Teach Their Children This."

"Art has been used to express feelings about every kind of situation since people could make marks on cave walls," Englebreit added. "I was happy to be able to do something that helped the Brown family even in a small way. And it's not over. It will never be over until black lives matter as much as white lives."

Street artist Damon Davis agrees. "Artists play a vital role , telling these stories and keeping history alive," he proclaimed in an interview with Mic. Like Firecracker, Davis created a series of posters; his also inspired by the popular "Hands up, don't shoot" rally cry. Taped onto local businesses that have closed after an outbreak of violent protests in Ferguson, the massive photos showcase a simple pair of hands, raised in solidarity with the gesture Brown allegedly made when Officer Darren Wilson shot him.

"[The posters] are important for people who may be on the fence to see," he explained. "Maybe they'll change their minds [and start supporting us]. And for those who aren't on our side ... now they know we're still here. And we're not going to back down."

Along with Woods' and Davis' work, an organization called Paint for Peace has been bringing art to the walls of Ferguson as well. Using boarded up businesses as canvases, the group aims to spread messages of hope and love with the help of local artists.

"St. Louis is a beautiful and resilient city . It is my home," Artbar STL owner and Paint for Peace founder Tom Halaska wrote in a message on Facebook . "I believe we are strong enough to come out the other side better than we started if people can listen, have compassion, and work to change what needs to be changed on so many levels. I have high hopes and expectations for our city. I know I won't be disappointed."
