This course builds upon the foundational knowledge of trade shows where Rickenbacker has exhibited, such as NAMM and other significant industry events, that you acquired during your undergraduate studies.
Let’s begin our discussion by examining a unique topic: "Department AC" labels. Who would like to volunteer to explain to the class what we’re looking at here? What were these for and during what years were they used?
What's your answer?

From @ronsvintageguitars:
Likely an ID for NAMM or some other trade show. I have two guitars with this kind of soundhole label: a 1967 366-12 OS in Autumnglo and a 1970 381 in Mapleglo. Guitars weren't bolted down back then and this was some additional ID using the tech at the time.
