15th May 1928 saw the debut of Mickey Mouse in his first cartoon Plane Crazy.
The animated cartoon showing Mickey trying to fly an airplane that he has just finished building. The cartoon wasn't very successful, which is why Steamboat Willie which aired in November of 1928 is often cited as being the Mickey Mouse's premier.
It was 48 years later that the first Mickey Mouse novelty phone was launched. The phone had a roatary dial and was later replaced with a push button model when touch tone dialing was introduced.
