Muscular Elvis Presley parody in Charlton comic book Go-Go #9 (October 1967). He's filming a movie with series regular Bikini Luv. One album glimpsed is Elvin Prisly Sings. His manager is called the Colonel.
Elvin and Bikini's engagement is announced as a publicity stunt, but neither one wants it, and Bikini calls it off in the next issue.
