Uncle Sam???

This is just a quick sketch that I drew in about a half an hour. I found an image off of the internet that really caught my attention... so I decided to sketch it. This is supposed to be a picture of Uncle Sam as a zombie. The actual picture has this figure with calligraphy at the bottom saying "Are you ready for a zombie attack..." however I decided I just wanted to keep it simple and leave it out for the viewer to figure out what I was trying to display.
