See link below to some great cast ads that would have run during the original airing of the Hazel show. I have never seen many of these and they are great. I especially love the ad where Don DeFore says "See your Ford dealer now and tell them Mr. B sent you"!!

A lot of these were keyed to specific episodes.

Not only did Ford buy the cast commercial, they got a fair amount of product placement in some episodes, too. Even some episode openings showcased Fords.

Although no Mustang ads were shown in this sequence, you can bet they had some ads for those, which went into production in 1964. A Mustang was showcased in some episodes.

Stevea, yes, I distinctly remember the exact episodes several of these commercials were from. These commercials are almost like watching mini episodes of the show and I love that.
