well, shows what I know, I never would have guessed more people would want the Superman 16 over the Action 48, which is why I chose these two examples, the Supes 16 went for $211 more than the Action 48, both sold in Comic link auctions this year,
For me the choice is easy, as Action 48 is probably my favorite all time GA cover, I've loved it every since I first saw it in the Photo Journals,.. now, don't get me wrong, I think Superman 16 has a great cover as well, the whole 40's look, the statue, Lois pining after Supes, and the knowing "wink" in Clark's eye, all add up to a classic Jack Burnley cover.
however...... the E. Church/Mile High copy of my favorite (and fairly scarce) Action war cover ?!?!?! no contest..
I'll take the Action #48 (then buy me a nice mid-grade copy of Supes #16 )
I'd also choose the More Fun #79.
