Update: Will passed away on February 2, 2015. He shared some of his artwork on his blog for two years, and my family is selling items featuring his artwork to raise money for JDRF and scholarships in his name at McDonogh and Rollins. Please visit the Hello Darlings Shop if you are interested in purchasing something!
My brother just started a blog to share his artwork. He is posting everything from T-Shirt designs to murals. Be sure to check it out here, wlhart.org!
