Cartoon Design Walking Advertisement

This is what a business in United States was looking for in their advertisement design

I would like a cartoon character design that is of someone holding a sign (similar to the walking advertisements that have the double sided signs to bring people into local businesses). I am open to ideas, though would like there to be a white space for the sign that is 300x250 pixels so I can put an add there.

I was thinking a man that is bald with some hair on the sides, maybe glasses? I like the idea of waving with one hand and the other perhaps pointing the 300x250 white space that the add will go to. Really the head, hands, legs and feet are the only part that need to be created, since the body is mostly covered by the add space.

As stated I am very open to ideas of the person to look interesting and open to artistic concepts or designs, though would like in the style of a cartoon type. Other than the 300x250 it can be of any size and I would like the graphic so I can put on a single web page to use. Read more
