When I was young, I remember cars with Ontario license plates had the slogan "Keep It Beautiful" printed on them. "Keep It Beautiful" was everywhere until "Yours To Discover" showed up. Then, for a while there was a split until all the "Keep It Beautiful" plates disappeared.
A little digging tells me the "Keep It Beautiful" slogan was used from 1973 to June 1982. In 1982 the slogan was changed to "Yours To Discover".
While I'm strolling down memory lane, "Yours To Discover" was the Ontario tourism slogan for most of my youth and they build a massive ad campaign around it in the 1980s. Here's a great spot from 1984.
