Sugar is Food, 1920
I think you’d have to go a long way to get a more half-arsed advert than this one, for Holland’s Everton Toffee. It simply states:
“Sugar is Food. So are Sweets. Try Holland’s Everton Toffee. Sold Everywhere. Advt.”
Hitching a ride onto a small piece about the price of sugar, its entire sales pitch is “Buy Toffee, it’s food.” Not even sticking in a spurious claim about being nourishing or anything. It looks like it’s trying to pass itself off as news, so it has to be made clear it’s an advert at the end of the line.
