The yellow sign on the right hand side of the picture says "Remember" in red writing up the top.. thats all it says on the whole sign and I like it that way =)

it would be good for a graphiti artist to write something like;

"Eggs, Milk, Cheese "

or perhaps;

"Your Name"

"Your Phone Number"

"where you live"

"we are watching you"
or even
"we build signs for a reason"

heh =)
