One doesn't see a lot of two-color advertising for major brands anymore. By two-color, I mean black (usually) for the type and one accent color printed on top of whatever color the paper is.

All three of these vintage two-color ads are from 1958. I found them at hmdavid.
Vintage ad for Martini & Rossi:
Vintage ad for Del Monte pineapple:
Vintage ad for Cool Ray Polaroid sunglasses:
