Oswald made a cameo appearance in the first animated sequence with both sound and color (two-strip Technicolor), a 2½-minute animated sequence of the live action movie "The King of Jazz" (1930), produced by Laemmle for Universal. However, it was not until 1934 that Oswald got his own color sound cartoons in two-strip Technicolor, "Toyland Premiere" and "Springtime Serenade". The Oswald cartoons then returned to black-and-white, except for the last one, "The Egg Cracker Suite" (1943), released as a part of the Swing Symphonies series. "Egg Cracker" was also the only Oswald cartoon to use three-strip Technicolor. Oswald's last cartoon appearance was a cameo in "The Woody Woodpecker Polka" (1951), also in three-strip Technicolor, which by then had become the norm in the cartoon industry. He also appeared in a 1952 theatrical commercial for the Electric Autolite Company, with his voice being provided by Dick Beals.
