In 1974 Swedish chocolate maker Cloetta ran an advertising campaign with ABBA
. You could win 200 of their new album "ABBA". I talked ny father, who at the time was working in Stockholm City, to go and visit the printer shop who made these billboards. And he did. He had to park a long way away from the printers and he felt kind of foolish like he was some kind of "sandwichman" promoting ABBA and Cloetta. I still have this priceless billboard in my collection. And I still love it.
