I saw this ad in the concourse of Cleveland airport coming home from Grandma's Thanksgiving. I can only assume that literally thousands of eyeballs gaze upon this ad.
But my eye focused on the barcode. Do I remember who the advertiser was? No. (Well that's money ill-spent.)
What do I see? The barcode. It's a UPC barcode. Definitely not the kind of barcode you'd expect to see used for ID and tracking purposes. At least I don't expect to see a UPC version A w/o human-readable characters used a such.
But that's just me.
