A Dan Harmon/Russo Brothers

Background
This was the production company of Dan Harmon and brothers Anthony and Joe Russo.

After the third season of Community, Harmon was fired from the series (only to be rehired for the fifth season, now producing under his own company, Harmonious Claptrap) and the brothers left at the same time. The brothers would later found a new production company, AGBO.

Logo (September 17, 2009-May 17, 2012)
Visuals: This is a logo that varies highly by episode, but in basic summary, we see an arts-and-crafts sheet (mainly Velcro or construction paper) laying on a hardwood floor (which also appears differently depending on the variant, though to a far less extent than the logo itself). The sheet reads "A Dan Harmon/Russo Brothers" (either in all caps, capitalized or lowercase), followed by a phrase below, such as: "Transportation", "Prophecy", "Tantrum", etc.

Technique: None.

Audio: None.

Availability: Seen on seasons 1-3 of Community.
