Marvel Comics' Seasons' Greetings

Here are three well wishes from Marvel Comics circa late 1960s/early 1970s. These come to us courtesy of Tom Brevoort and Sean Howe. (Notice how I got to have a little fun with the apostrophe in the usual "Season's Greetings" much like DC Comics is with its current Worlds' Finest title.)

All three of these appear to have been pencilled by Marie Severin (with the one below probably inked by Frank Giacoia). Like The Thing says, Season's Greetings!
