late 70's early 80's MILK ad

I've been searching for this photo for years... cannot find ANY picture on the net.

Milk tanker trucks, and ads in early 80's (in Arizona at least) showed a beautiful brunette in aerobics wear with legwarmers on, and a towel over her neck, if I remember correctly.... sitting on floor? with one leg crossed over in front

This was VERY EARLY "Milk, it does a body good..." campaign (again, if memory serves), but again, I have searched Google and Bing images (1000's) and not found this picture using MILK with LEOTARDS, LEGWARMERS, 'DOES A BODY', 1980's, VINTAGE ADVERTISING CAMPAIGN, etc...

Stumbled upon your site, and thought maybe someone could help.

This photo would be nice, with name even better

Thanks in advance.
