Nice. Jackson Browne sang his song about Cuba on The Colbert Report the other night, and he had me nodding in agreement about what a STOOPID embargo that is. I wish more musicians would write contemporary songs that make you think.
I like you image. The straight presentation is excellent, just a found scene well done. You might want to correct the perspective so that the storefront doesn't fall backwards creating a distraction. Also, as the image speaks so well, I'm not sure about texting it. The Flag is a strong emotional image with many meanings for many people.
I've not posted any but I've done similar work that I consider vernacular flags. That is, flags is every day usage.
