#2 I really like the colors and the playfull font, the flower on the beginning, not sure if it will be well readable from a moving car [when on a road sing], but I would give this design rank 1 for printed material and for web use
... well I ment entry #4 which I ranked 2nd ... the numbers and the ranking is a bit confusing me, sorry: so my comment from 3:02 am belongs the Entry #4, ranked as 2nd
