Kona Monarch of Monster Isle #14 from Dell Comics
I know this is showing a battle between Kona and a T-Rex, but when I see this cover all I see is Kona cleaning the T-Rex's teeth.  Tell me he does not look like he is examining the dinosaur's teeth and cleaning between them.  Even the dino's eyes have a look like he is at the dentist.  Funny stuff.
