Many of the images I make in class are used to illustrate ideas quickly and simply. For example, the word “courting” appeared in an article about a company courting another for a possible merger. I made a clear analogy of one company trying to woo the other with a simple sketch of a prince courting a princess. The students had a laugh and I used royal characters to reinforce the formality of the word. It’s silly, but it works even in a business context.
Of course, you should decide for yourself what’s appropriate for your group. Many of the images here might not work for adults and are better suited for kids. I encourage you to use a mix of styles to maintain interest and fun.
