These chalk artists were clever. Their business model was to create multi colored homages to individual countries. They then exhorted the crowed to support their home country by putting coins on their country’s flag. Brilliant. I mean who wouldn’t support their home country with a coin, especially when you can see that the flag next to you has more coins than you. As I watched the surrounding, and admiring crowd, I saw people pointing out to their friends how much money each flag had collected. I was impressed with both the art, and the creativity in getting tourists to part with their money, all in the service of national pride.
