Fantastic Four #147 was my first ever FF comic book. My grandpop bought this for me at Clark Air Base and I was enthralled. Along with X-Men #19 (the Mimic), they were some of my first ever comic books and they turned me into a lifelong comic book fan. While I still have the FF issues, I lost X-Men #19.
This three-issue arc features the first ever Johnny Storm in a red FF costume, Thundra, Medusa, and a battle vs Namor for Invisible Girl.
