I have always found that the art of postage stamps to be an area of massive inspiration as a designer. I see the design of stamps as a representation the times and the goals of countries in how they want their fellow citizens and the world to see them. Social movements, history, current events, culture and propaganda are shown in this smallest of formats that showcase style and design. Karen Horton has set up a Vintage Postage Stamp site on tumbir with some excellent examples for inspiration. Karen also keeps busy as the co-founder of the wonderful design:related website (great inspiration in it's self) and as an Art Director at Little, Brown and Company. Thank you Karen for spreading the word in the design world.
