Davey, This might be information way older than your quest or interest, but from the end of WWII up through the 60s and 70s, ads in the so-called shelter magazines like Better Homes & Gardens, sometimes used celebrities to endorse products. Fred MacMurray (sp?) and his wife June used to pose with gas appliances, including the WP gas combo, even though on My Three Sons, in the good early days, the kitchen had a Frigidaire Custom Imperial range and a lower end of the line Frigidaire laundry pair.
Bing Crosby was pictured with something domestic at one time, but that was before his sons started committing suicide because of their abusive childhoods. After that, I don't think he was such a sure draw.
In an early 1950s issue of BH&G, the cover had a picture of Dinah Shore in the kitchen at her California home. She was married to the actor George Montgomery. She was photographed cooking on the weirdest electric cooktop I have ever seen. Actually the tour of a celebrity's home was a feature that regularly appeared in those magazines in the 50s and 60s. I always looked through them to see the kitchen appliances. I remember the home of Dennis Day. They had a bunch of little kids and had two Frigidaire spray tube dishwashers from the early-mid 60s. I believe that there was a place near the back of the issues where it was possible to find the names of the appliances and furnishings in the articles. For many years BH&G also had an index to advertisers and Appliances, Major was the first heading so you could see the wonderful ads for your favorite brand or category of appliances.
