I guess it would be impossible to have too many Barney Baxters.
Here's my copy.
I see that they both have the distributors "A" marking in the same spot. They must be long lost cousins.
I get a a laugh out of how your first name is written in small letters in the puff of smoke, and the sweat beads and question marks next to the cockpits of the downed Nazi planes (that was the detail that gave away the answer for me, not the second picture you put up).
Have you read the book? The "real" Frank Miller was a very good cartoonist, mixing a few "bigfoot" characters-- Gopher Gus on the left -- with more realistic ones. It's strip reprints, but the storyline is surprisingly strong. Most of the adventure is in northern Alaska and the Eskimos (Inuits? Aleuts? Tlingits? I forget) are handled well, not as "stupid aborigines" for comic effect, which would have been typical at the time.
If I remember right, there's no dogfight with Nazi planes inside the book.
