I love The "Bolg" of "Unnecessary" Quotation Marks. It is a great site with many good pictures of bad punctuation.
I saw this today: http://quotation-marks.blogspot.com/2008/10/you-should-have-seen-how-they-were.html
The quotation misuse is bad enough. I particularly find the lower-case i in DAViD to be dumb. Whoever made the sign should be forced to repeat elementary school.
