I made somthing like that about 3 weeks ago for myself. Its not digital print though, just cut out ov white vinyl and applyed to my winshield. I have been designing a digital print one for about 4 weks now. I'm tring to make it as simple as posible and still look cool at the same time. Mine is just a KANSAS Zombie Hunting Permit. Reason its taking me so long to make it is I do it when I'm at work borred and actualy think about it. So I have actualy spent only about 2 hours on it so far.
What is LIFE you ask? Well LIFE is that thing that takes a BIG FAT DUMP on all your HOPES and DREAMS. That is what LIFE is.
