How to confirm

Is this for real? Is the sub-mariner really in the public domain? How could I confirm this? Who would I need to contact?Andrewacosta117 (talk) 01:13, April 16, 2017 (UTC)andrewacosta117

  • Might I suggest reading the "Notes" section of the article? It might provide some answers for you. LogiTeeka (talk) 10:31, April 16, 2017 (UTC)
  • Yes I have read the notes but I wanted to confirm that the copyright for Marvel Comics issue one was not renewed on it 28th year. Where or who would I contact to confirm this?Andrewacosta117 (talk) 10:49, April 16, 2017 (UTC)Andrewacosta117
