Logo: At the end of the credits, we see the DFE Films logo (as in the 2nd logo). Below it, we see the text "A DePATIE-FRELENG PRODUCTION". Variants: On The Cat in the Hat, the cat's hat appears on "films". On The Blue Racer, the logo appears on a light blue background, we see the letter "D" fading-in and flashing in multi-colors, followed by part of the letter "F" fading-in and part of the letter "E". The line fades in through the letters "F" and "E" to reveal the 1969 logo. The logo would turn solid red and the word "Presents" fades-in below. Sometimes, it would zoom-out while animating. FX/SFX: None. On The Barkleys, it's superimposed, otherwise placed on a background in the color scheme of the show's credits (i.e. pink on Pink Panther). And, on the 1971 TV special On The Blue Racer, the logo would sometimes zoom-out while animating. Music/Sounds: The opening/closing theme to the show. Availability: Should still show up when DFE shows and specials from the late '70s are reran, as it is in-credit and usually left alone. It's most likely to be found on Dr. Seuss special from 1971-1980 VHS tapes, DVDs and Blu-rays.
