Some say it's journey into mystery 83 but thor and loki was in venus 12 a canon marvel book before it? They don't look or act like the later versions but even marvel changed it to their first comic then changed it back later in handbooks.
So what is thors first appearance? You could say venus was a prototype but again it's a canon book. So what do you guys think?
