If there this one guarantee when you enter into the freelance illustration business, it is that you will be dealing in a lot of visual cliches. Yesterday had another crack at drawing a caduceus for Barrons, and I’ve done plenty over the past 27 plus years. Like their good friends: Uncle Sam, Lady Justice, the Top Hatted Millionaire, the Cap and Gown Graduate, The Bear and the Bull, and too many others to mention, they pop up again and again. Below, I’ve collected a sampling of caduceus illustrations from other clients (Wall Street Journal, Newsday, the Chronicle of Higher Education, Chicago Magazine, among others) just for fun.
