In my perambulations thus far, I've seen a handful of these signs, mounted on traffic poles, directing people to McDonald's. Made of metal and well-weathered, they look far more permanent than the countless other illegal ads — mostly plastic signs — adorning the street furniture of New York City, giving them a perverse air of legitimacy. I particularly like this one: not only is it attached to government property; it also encourages people to spend government funds at McDonald's. (For the record, I'm fairly certain you can't use food stamps at restaurants in New York, at least not yet, which makes this sign even more bizarre.)
