Fantastic Four #52 (1966) CGC Marvel Comics
The Fantastic Four are given a flying craft by the nation of Wakanda as a gift, as part of an invitation to visit the mysterious African country. Intrigued by the technological marvel brought to them, Mister Fantastic agrees. Their visitor then contacts the leader of Wakanda, T'Challa, also known as the Black Panther. T'Challa and his people rejoice at the news and they raise the panther idol high before he enters the sacred temple and dons his ceremonial Black Panther garb.
