I want to know the answer to the following question:
What was Marvel's self-hosted comic book convention called?
All the background I'm provided with is that "At the 1975 event, Stan Lee used a Fantastic Four panel discussion to announce that Jack Kirby, the artist co-creator of most of Marvel's signature characters, was returning to Marvel after having left in 1970 to work for rival DC Comics.". Is that enough to answer the question?
Answer: no
