"Each of these jars of honey has the name and address of the producer. How about that for provenance in the supply chain?"
A poor photo from a shaky hand, but the point is well made. As we want more information about what we buy and what we eat, the logical extension is to put the name and address of the person who made the food on each jar. In this, food production becomes more craftsman like as each jar is its own work of art, with the artist signing each jar.
