This poster is designed by Ruofei Du during his EXPO 2010 volunteer-ship in Shanghai. I cannot find the original design PSD file. The poster was printed physically and carried to our volunteer site. The face of Haibao (EXPO 2010 mascot) was cut off for kids to take photos 🙂 Kids-poster interaction 🙂
I also designed and printed physical badges for EXPO 2010 volunteers.
