We have letters in two sizes that can be assembled with certain characters like smiley faces and American Flags, to spell out most messages. Our Aircraft can fly banners up to about 50 characters long! Or, you can have a very large billboard created just for you. Billboards can be quite large, even up to 50' tall and over 100' long! These last for years and can fly many, many times so you get quite a bang for your buck!
