It’s a circus issue. But no, we don’t get the Circus of Crime. Instead, we get Taskmaster (who we know from Avengers #221 likes to hang out and recruit talent from circuses). This is just the second appearance of the character.
In the end, Tasky is arrested and the circus mind-reader, Vance Astrovik, decides to hang out with Thing for a while.
