Bruce McCorkindale Re-Creation of Jack Kirby and Vince Coletta's Thor #145 Cover
Based on Thor #145, October 1967. I always loved this issue.
Grand Comics Database story synopsis: "Odin defeats Forsung and demands all Asgardians return. Thor refuses and his powers are removed (except his Asgardian Strength). The Ringmaster hypnotizes Thor into joining the Circus of Crime."
