Costumes from the film were on display at D23 Expo 2017 and the 2017 San Diego Comic-Con,[179][180] with Coogler, Boseman, and other members of the cast presenting exclusive footage of the film at the latter event, to a standing ovation from the audience.[181] In September, Coogler, Gurira, and Moore participated in a panel at the Congressional Black Caucus Foundation's Annual Legislative Conference, where exclusive footage from the film was also shown and met with a positive response.[124] On October 16, 2017, a full trailer was released. Dave Trumbore for Collider praised the trailer for showing an "unmistakable sense of style" unique to the character,[182] while BamSmackPow's Brendan Day felt the trailer "does everything right".[183] Writing for Rolling Stone, Tre Johnson felt the trailer showed T'Challa as "someone with the arrogance of [John] Shaft, the coolness of [Barack] Obama and the hot-headed impulsiveness of Kanye West".[184] A few days later, Marvel Comics published a prelude tie-in comic focusing on one of T'Challa's first missions as the Black Panther set around the time of Iron Man.[185] The first College Football Playoff National Championship halftime show was organized by Disney for the 2018 championship game, with Kendrick Lamar performing to promote Black Panther: The Album and the beginning of ticket sales for the film.[186]
