I have one of those oval stickers with a Delta and a Zeta symbol on it. I thought it was cool because when I was a kid and lived in Germany, those were the stickers we had to put on our cars that said what country we were from. Ours was USA Wish I still had one of those! I kind of like them...it's always fun to try and figure out what the letters stand for. Better than staring at the dashboard in traffic
