I want to know the answer to the following question:
In what issue was Namor, The Sub-Mariner introduced?
All the background I'm provided with is that "The company's first true editor, writer-artist Joe Simon, teamed with artist and emerging industry notable Jack Kirby to create one of the first patriotically themed superheroes, Captain America, in Captain America Comics #1 (March 1941).". Is that enough to answer the question?
