Elsie the Cow.  She's still around since the 1930's.  She's still working for Borden after all these years.  Throughout her career Elsie has been awarded  honorary degrees which include Doctor of Bovinity and Doctor of Ecownomics to name a few.  Not only has she represented perfect milk products, but also played a roll during WWII by selling War Bonds.
Her husband Elmer the Bull started our promoting Borden milk, but later made a name for himself when he transferred over to the Borden Chemical Division.
