In the early summer of 1927 Disney finished the first Oswald cartoon. It was named "Poor Papa" but Universal was not very satisfied. They had expected a more Charlie Chaplin-like character and thought Oswald was too big and too weak. Disney agreed to make some changes and the cartoon was not released in theatres at the time.
Instead, Oswald's second-produced cartoon was submitted for release: "Trolley Troubles". Universal was pleased and the short was released by Universal on September 5, 1927. In the cartoon, Oswald is a trolley conductor. Due to road trouble, however, the trolley car goes completely out of control.
The press loved the new cartoon series Walt made and Oswald became a true hero. From that moment on, a new cartoon was released every two weeks. As for "Poor Papa", it too was released eventually in theatres, although Universal held it back until 1928. In total, nine Oswald cartoons were released in 1927.
A re-release was completed on November 23, 1931 after Walter Lantz Productions took over. This re-release was completed with music and sound effects.
