Vinnie...
I searched the TV Guide database. Lesley Ann Warren was on the cover one time on February 3, 1990.

In the January 23, 1965 issue, Chuck Connors was on the front cover and there was a story on that Cinderella production with her in it. I did find an ebay page with that particular issue being sold. There are some thumbnails of the pics (maybe not all of them) on that auction site:
Unfortunately, no pics of her in curls.... the only Cinderella I found with the sausage curls was Mary Pickford.
