I read the Doctor Strange & Doctor Doom: Triumph and Torment collection today. Thank you for that story, Uncle Rog! I think that was the first, full Dr. Strange story I ever read. I know I'd read his appearance in the John Byrne Fantastic Four story where they battle Mephisto, but other than that, Dr. Strange was a blank slate to me. This was a great introduction to both Drs. Strange and Doom. Mike Mignola's art is also a pleasure to behold.

These are $2.99 today, along with Masterworks Vol. 1.
