During their unveiling Thursday, Mercado President Maria Ontiveros called them a celebration of Mexican culture.
"We really hope that this piece not only inspires Hispanic cultural pride, but Quad City resident pride. And that visitors who drive by and see this think that the Quad Cities is a cool and welcoming place to be."
Chicago artist Czr Prz (Caesar Perez) says it took about four weeks to finish the murals.
"We have the Day of the Dead which is a huge, huge holiday for us. And just like the celebratory aspects of what it is the people have brought here - a lot of the dance, a lot of the food, and even the natural flora and fauna which is why we have the marigolds represented throughout it."
The murals include a butterfly to symbolize migration, and a cowboy with the likeness of Bob Ontiveros who founded Mercado on Fifth.
Perez has completed large-scale murals like these in Moline, in North America and Europe.
