The first logo used was a static shield with the letters WB on the bottom and a picture of the Warner Bros. studio on the top. From 1929 to 1933, the logo seems to have been completely abandoned. Occasionally, however, (mostly in features from 1929 and 1930) a First National film would bear the old animated logo for that studio. During these years, feature films opened with the main title along with the vitaphone logo. The Warner Bros. logo was used from 1931 to 1933 on the title cards of cartoons. The Warner Bros. logo re-introduced in live-action films around 1934. The current WB logo shows a reflection of the WB studio, which then slowly spins away from the camera revealing the WB logo. The music in the background of this card is "as time goes by", popularized in the 1942 Warner Bros. film Casablanca.
