This is the first animated cartoon, released in July 1913, heck, it’s one of the first movies period. No, it’s not “Steamboat Willy.” That was 1928. And Gertie the Dinosaur was done in 1914.
It’s called ” The Artist’s Dream; The Dachshund and the Sausage.” It shows a live cartoonist, J.R. Bray, drawing the cartoon and then shows the animation.
