For the last five years, the Mount Pleasant Culture, Arts & Pride Commission has been turning silver traffic signal boxes into works of art selected from local artist submissions. One of the applicants that year was Bob Graham, also known as the Saltwater Cowboy, a renowned Lowcountry painter. He often walks around downtown, taking pictures of people for inspiration.  On one excursion many years ago, he was with his girlfriend outside of Henry’s when a boy came up and offered to sell them a palmetto rose. Graham appreciated how the roses contrasted with the skull and crossbones on the boy’s shirt. He purchased a rose, explained to the boy that he was an artist, and asked if he could snap a picture. He then turned the picture into a portrait and submitted it.
