You are so careful about ensuring the designers rights!
That's wonderful, actually. :))
However, you could quite safely UNSEAL the contest after choosing the winner without compromising any of ours(designers) rights because if any of the other top rated entrants want to withdraw their entries( since you had not selected them as winners) they can do that any time!
But, with all due respect, do whatever you feel right and once again this caring attitude is much appreciated!
I enjoyed coming up with an original typeface #483 for your brand. It was a great deal of fun creating a look that is modern and tire like. I realize that the finish can change from a gloss to something more to your liking. I appreciate you suggestions for improvement. Good luck.
