Jumbo Pictures

Background
Jumbo Pictures, Inc. was an independent animation production company founded by animator/children's' book author Jim Jinkins (creator of Doug) in 1988. In 1996, Jinkins sold the company, and the rights to Doug with it (except Nickelodeon still owns the rights to the Nick-produced series), to The Walt Disney Company. Jumbo Pictures continued operations until the cancellation of the Playhouse Disney cartoon series PB&J Otter in 2000, and was folded into Walt Disney Television Animation after that. Jinkins is still active in animation, forming his current production house "Cartoon Pizza" in partnership with David Campbell in 2001, though the company went dormant after the last episode of Pinky Dinky Doo aired.

1st Logo (August 11-December 8, 1991)

Logo: On a dark blue background, we see a large egg with "JUMBO" in front of it, and "PICTURES" below in far smaller type font on a black rectangle and the word "INC." in a much smaller font below "PICTURES", with the text "GRADE A QUALITY" on the bottom with "A" bigger than the rest of the letters.

Trivia: On Doug, the title character lives on 21 Jumbo Street, an allusion to the company. The character Skeeter Valentine also has a Jumbo Pictures poster in his room.

Technique: None.

Music/Sounds: A beat boxing and scatting tune (based off a recurring music piece heard on Doug) that carries over to the Nickelodeon logo.

Availability: Rare. Seen on the first season of Doug.

2nd Logo (September 13, 1992-October 15, 2000)
Logo: On a vanilla cream colored background, we see the same Jumbo Pictures logo from before, but brighter. The surrounding area dims as the egg's shadow becomes visible and the text becomes 3D, and the text "GRADE A QUALITY" fades in below the egg.

Variants:
 * In 1999, the background became light blue. This was first seen on split-screen credit airings of Disney's Doug when aired on Disney's One Too.
 * On Disney's (Brand Spanking New) Doug and PB&J Otter, the logo is shifted up a bit and there is a copyright stamp under it.
 * On the 1999 film Doug's 1st Movie, the egg is smaller and the background is a different shade of light blue. Plus, "GRADE A QUALITY" is a bit bigger. The egg is also more realistic and there's no copyright stamp below.
 * On 101 Dalmatians: The Series and Sabrina: The Animated Series, an in-credit version of the logo is used (text only).
 * On Doug's Big Game for the Game Boy Color, the logo is smaller and on a white background. "GRADE A QUALITY" is also in red.
 * On Allegra's Window, the animation is slowed down, and on Season 1 episodes the logo is darker.

Technique: The shadow animation. Early CGI.

Music/Sounds: Either the closing of the show's theme or a snippet of background music from Doug consisting of a synth organ and muted trumpet-like vocal humming that continues into the Ellipse Programme and Nickelodeon logos on Doug or the Time-Life Kids logo on The Beginners Bible (composed and performed by Fred Newman).

Music/Sounds Variants:
 * On Allegra's Window, a rooster crows as the music from the Topstone Productions logo trails off into the logo, then we hear a dramatic rendition of the song "What a Wonderful Day". On some episodes, the music is low-pitched.
 * On Doug's 1st Movie, you can hear a sampling of the Disney's (Brand Spanking New) Doug theme music.
 * At the end of the Nickelodeon Doug episode "Doug's Christmas Story", a rendition of "Deck the Halls" plays, going into "Jingle Bells" once going to Ellipse Programme and the Nickelodeon Productions logos of the time.
 * At the end of the Nickelodeon Doug episode, "Doug Throws a Party/Doug Way Out West", the music is delayed on some airings.
 * During airings of Disney's Doug on Disney's One Too with split-screen credits, the 1988 music for the second Walt Disney Television logo would play over it, also going into the said logo.
 * On NickRewind's airings of Nickelodeon's Doug with the split-screen credits from 2011 until 2015, the beat-boxing tune was abridged in order for it to end on this logo so it wouldn't play on the 2009 Nickelodeon Productions logo that plastered the usual NAS "Haypile" logo.
 * On a 1998 ABC airing of PB&J Otter, it plays a generic theme over the logo, along with the Walt Disney Television & Disney Channel logos.

Availability: Uncommon. It was seen on Doug beginning with its second season. The show used to air as part of NickRewind on TeenNick, but in December 2021 the block was reduced to air only iCarly and Rugrats; iCarly would be the only show left on the block in January 2022 before the block's closure a month later. Disney+ prints of Doug preserve the logo. It was also seen on PB&J Otter when aired on Disney Junior (and kept intact on Disney+ prints of the show) and the short-lived series Hoyt'n Andy's Sportsbender. Home video releases of Doug, Allegra's Window, Doug's 1st Movie, and The Beginners Bible keep the logo intact. The in-credit text version is rare, and can be seen on 101 Dalmatians: The Series, which last aired on Disney Junior in 2013. However, episodes can be available to purchase on the iTunes store, as well as streamed on Disney+, and is also seen on the show's VHS release 101 Dalmatians Christmas.

Legacy: Those that are fans of Doug would consider this logo a favorite.
