When retail commercial items become mainstream enough to earn a barcode—Universal Product Code (UPC) numbers—one can safely assume that these items have earned some degree of widespread popularity.
Perhaps one day, the same could be said about the barcode variations in this cluster! Although they’re a bit more quirky and artistic than the run of the mill retail item, it would be interesting if some of them managed to earn an actual UPC number. My money would be on a the temporary barcode tattoos!
