I've been working with my friend Jonathan Wiese of 3.2.1 on a marketing program for Children's Cancer Research Fund. With his direction, I submitted this idea as my favorite for a series of 4 postcards. Since it has a child-like flavor, I thought it hit the mark completely.
The client couldn't make the connection between old technology (planes, trains, mining, hourglass) and the new innovations their research creates. So, we settled on the idea below... which I also liked.
