The Mighty Thor volume 3

From Amazon:

Thor is back! And in a story only J. Michael Straczynski could tell! Returned to the pantheon of great Marvel heroes, the Asgardian God of Thunder is reunited with the mortal form of Dr. Don Blake. Together, they must reckon with the legacy of the mythic Norse kingdom and the awakening of its immortal heroes - but in a world that may not want them back!

After issue #12, this series reverted back to volume 1 numbering with issue #600.

After issue #621, the series returned to its original 1950's/1960's title name: Journey Into Mystery, with issue 622. The series featured Loki as the main character from that point on.

Thor got a new ongoing series for himself, The Mighty Thor volume 4.

Request filled for the legendary MrDowntown!

I grabbed these from zlennyk's https://thepiratebay7.com/torrent/7238840/ , which is seeded -- but the first 12 issues were re-numbered (#588-#599).
