Longest running cartoon strip by a single artist

According to Official Guinness Records,

Since January 1940, Jim Russell (b. 26 March 1909, d. 15 Aug 2001) of Kirrawee, New South Wales, Australia, drew the comic strip The Potts, published in Smiths Weekly until 1950 and then daily in the Melbourne Herald until his death. Thus, it ran for over 61 years.
The Potts were originally created by Stan Cross, who worked for Smiths from 1920 until 1939. Russell was his assistant, but was nominated to take over drawing all his features. When Smiths closed down, Rupert Murdoch bought the rights to the strip, allowing its continuation.
