Hi Duke,
No problem! I had the sign done that way already, so it was matter of just switching them out. My reference to the illustrative work was more about having to redraw. For instance the vette in another color won't be that big of deal. But if you needed it at a different angle, then it starts from scratch, it would be the same as if you wanted a 57 Bel Air, it would need to be hand drawn. Feel free to suggest any changes, some revisions are easier than others.
As for the sign, don't worry that was an easy one since I had it done previously. My thinking with the tattered sign was it to give it an old retro feel. Mixing both an old feel with a modern look.
