Marvel's best-selling title was Nick Spencer, Ryan Ottley, and Cliff Rathburn's Amazing Spider-Man #11 at #6, one of the three Marvel titles that made up the rest of the Top 10.
Marvel was the top publisher in December, with a 38.57% dollar share and 44.09% unit share. Despite their dominance in the comic book Top 10, DC was a fairly distant second, with a 31.51% dollar share and a 30.75% unit share. In third was Image Comics at 8.73% in dollars and 9.06% in units.
The discrepancy between Marvel and DC's respective 'wins' for the month seems mainly due to the fact Marvel shipped 90 comic books to stores in December, compared to DC's 52.
The final year-end 2018 sales were previously reported, so sales comparisons are somewhat anticlimactic, but comic book dollar sales were up 9.29% versus December 2017, and graphic novel sales were down 26.35%, for a total of a 2.26% deficit versus last year. Again, that puts year-end 2018 total sales down just 1.08% in dollars versus 2017 and down 5.98% in units.
