Black Panther by Jack Kirby #1

Black Panther helps Abner Little, a member of the Collectors, recover the Brass Frog, an ancient time machine. Due to its dangerous nature, the Frog had previously been hidden away by the Black Panther's grandfather, Azzuri, but was taken by Alfred Queely, a fellow member of the Collectors. After getting the Frog, the Black Panther and Little are attacked by Princess Zanda, another member of the Collectors, for control of the artifact. During the battle, the Frog is activated and a mysterious creature, Hatch-22, appears.
