A sneaky flower dealer near Sunset and Vermont in Los Angeles has a sign on the sidewalk that tricks drivers into thinking it sells roses for $4 a dozen.
But if you get down on your hands and knees and use a magnifying glass, you can see a tiny "1/2" in front of the large "DOZ,"and an equally miniature "99" above the dot after the "$4."
That said, the sign's design and colors are quite attractive.
