Diaz Sign Art of Pontiac, Illinois is a family-owned and family-run shop that started up back in 1979. Designer Joe Diaz and his brother Ben currently work at the shop with their parents Bill and Jane Diaz. Today the business works with logos, branding, vinyl, and printwear. Another thing they’re really good at is hand-painting murals. In addition to commissioned mural work, Diaz Sign Art is an active participant in the Walldog movement.
