German advertisement from the 1970s, "Ei, Ei, Ei .. something"

My brother and I are trying to find the wording of an advertisement we remember seeing on the side boards of European ice rinks back in the 1970s-1980s. We would see this when ABC would show things like the World Figure Skating championships.

It was written in the old style Gothic lettering used for German (I apologzie for not knowing the exact name of that style).

The ad looked to us like “Ei, Ei, Ei, Ei, Verputen” or something along those lines.

I know this is vague. But am I anywhere near correct on this and just what was that an ad for?

Ei, Ei ,EI, Verpoorten

A german Egg liqueur
( ei is german for egg)

Verpoorten, THE big name on the German egg liqueur market. “Ei” (pronounced “I”) is German for both egg and a somewhat positive interjection that nobody uses outside of egg liqueur ads unless talking to a baby as if it were an idiot.

Thank you both very much.

My brother and I will erect small churches in your honor.
