A little while back our friends from Dinin’ Hall started a project to beautify a local spot with the Ohio Birds Mural. We helped them out with small signs to identify birds and donors, and the main large sign explaining the project.
The project was on Kickstarter (its over now), but there is plenty of information on it if you are looking for some. The large sign is made from 1/4″ thick aluminum. We sprayed the aluminum with dark grey primer, and then machined the aluminum through the paint. The result looks great and is very easy to read. The sign measures 24″ x 36″.
