“Go Psycho with Elvira!” was a promotional campaign that ran from 1989 to 1990 to promote PepsiCo’s Mug Root Beer and Slice soft drink brands. The campaign involved a contest to “win a party with Elvira at the Bates Motel, Universal Studios Hollywood”, as well as Elvira cups sold by the fast food chain Wienerschnitzel.
The campaign’s slogan uses Bordonaro Vampire, which is also used in Wienerschnitzel’s television ads.
