Elsie the Cow - Brown Jersey cow mascot for the Borden Company who appeared on various occasions (as a marionette) during THE BORDEN SHOW/NBC/1947. After the Borden Company began an ad campaign featuring their logo of Elsie the Cow in 1938, they needed a real cow to be their representative and so they recruited a bovine named "You'll Do Lobelia" (born at the Elm Hill Farms in Brookfield, Massachusetts in 1932). In 1940, Elsie got a partner, a husband named Elmer. Both Elsie and Elmer (the mascot for Elmer's Glue) have appeared in print, and media advertisements since the 1930s. Elsie the Cow beat out actor Van Johnson and U.S. Sen. Robert Taft in a 1952 recognition poll surveying America's most familiar faces. In the 1990s, after 15 years in retirement, Elsie was resurrected for an animated TV ad campaign. Actress Hope Emerson provided Elsie's voice in a variety of TV commercial spots in the early years of television.
