The Power and Influence of Illustration [PDF ebook] 
Achieving Impact and Lasting Significance Through Visual Communication

Delving into the rationale behind influential communication,
The Power And Influence Of Illustration helps you understand how to work with a message to create convincing illustrations for your audience.
Alan Male explains how illustrative imagery can lampoon, shock, insult, threaten, subvert, ridicule, express discontent and proclaim political and religious allegiance. He explores how its tools have been used in the past, and looks at how contemporary illustrators can use their own work to persuade – and discusses where the line between persuasion and propaganda lies. These issues are explored using hundreds of full colour images from international artists, both contemporary and historical.
