You are an apocalypse dreaming of butterflies
we are a patchwork of miracles.
No, concept behind Alfred puts mah money far away from that book.
Be careful when speaking. You create the world around you with your words.
To put it in proper perspective, in the direct market it sold about 16k copies it's first month. In March, the top item (Walking Dead volume 1) sold less than 6k. Now, I'm not implying Superman: Earth One has sold more than Walking Dead volume 1, that Walking Dead trade has been in print for years and has easily pushed more than 500k copies in that time and new Walking Dead trades push 20k+ in comic stores alone, but that Superman: Earth One sold better than most new trades and original graphic novels do. Batman: Noel for example only pushed about 13k in it's first month and that was considered a pretty solid success.
I'm not entirely sure what decent numbers would be for an OGN to be honest, but it was in seventh place for DC's offerings of the year behind: Watchmen,Batman: Year One,V For Vendetta, Dark Knight Returns, Killing Joke and Hush, all of which are pretty old. To me that sounds like a mild success at best especially considering the advertising it got.
