A new product surfaces from Du Pont Co. in a campaign backing Zodiaq. The new surfacing material is made primarily from quartz crystal. Gabriel Diericks Razidlo, Minneapolis, created the trade ads, in which the mineral is conspicuously absent from a rock specimen box, a timepiece and a necklace. In its place is the line: "Gone on to bigger and better things." Copywriter: Tom Gabriel. Art director: Matt Johanning.
