MissyWeitzel I have heard it was 1981.
I loved going to the PSDA tuber packing party and being too shy to talk to ADS celebrities. Martin Kral, Dick Parshall, Linda DeRooy Holmes Cook, Christine Tareen among many others. Mr. Parshall cheered on a winning photo contest entry of a Clearview. I was sitting at the table packing tubers "A" through "C" and saw all of the ACs come in. I was delighted that I got to tell my table-mates what AC FBG stands for.
