Thor by Steve Rude

Purchased from Fanfare-se.com. I have always loved Steve Rude, & I have always loved Thor. So when I saw this piece on the website I got it. It is actually the companion piece to the Captain America. They are both on the same 11 x 17 sheet. Cap on the left, & Thor on the right. The website said that these were used for the indicia on the upper left of the comics sometime in the 80's or 90's, but I haven't been able to verify that. If you can help, please shoot me a message.
