Four color/process color logo for Chorus America.
While this is an EPS file, it is vector art and can be opened in Illustrator, Draw, etc. for editing. It was saved as an Illustrator V8.0 file so almost any version of Illustrator, Draw, etc., should be able to open it. The raster image is a 300DPI PNG file with no background color.
If you choose or need to make a grayscale version, may I suggest that you select all of the (formerly) green areas and rase their grayscale value to 50^ - 60%. This will make them dark enough to be easily seen, but still light enough to differentiate them from the (formerly) Navy Blue areas.
