This week, my sister-in-law Paula will be turning 60. In addition to her family, people all over the world are celebrating her big day through their artwork. She’s showing up in art galleries, on billboards, posters, magazine covers, graffiti art, and even in puzzles and her own currency. (There were also some tributes which featured a black and white photo of Paula as a young girl, with her younger brother trying to horn in on the picture.) Happy birthday Paula!
