Vendor is selling jewelry on the corner (outside the Metro).
They're advertising:
Products Of The Highest Quality
But would you even expect to get the highest quality jewelry off the street.
As nice as these products may be (and he may be), I don't think anyone would really believe this.
So while the ad grabs your attention and makes you look, it doesn't make you believe.
Advertising and branding has to be credible to reach their intended audience or else it'll just come off as fool's gold. ;-)
