Wonderbra Yellow Safety Line:
This ambient idea plays on the yellow safety lines at above-ground MRT stations, which tells people how far from the track they need to be to be safe. A second yellow line was used to demonstrate that, with the bust-enhancing effects of Wonderbra, those who use the product need to be even farther back.

Only works in NYC.
The rest of us knew nothing about the dashed yellow line. We just assumed the "WonderBra" line was the next public place being sponsored by a company to get widespread advertising.
Room for another line 6 inches further back marked "Viagra"?
Nice idea for a safety line. Good shot.
Clever. I like when ads force a tiny bit more thought than "Ooohhhh, pretty."
Ooohhhh, pretty.
