Type and Imagery.

I found some simple imagery to portray 'charging': A battery, a car batter, an ipod charger, and a plug. I used the outlines of these 4 things and put green tire tracks going through them. I thought this created aesthetically good images that portrayed the message I wanted to get across.

Also I tried out 4 different type faces for the denomination. I choose the family of Myriad because i found the type to be clean and clear and legible for my stamps.
