I think the book is doing great considering the current market.
Speculators are driving up prices due to movies and TV shows. Invincible has neither. Invincible #1 is as expensive as it is due to the comic book alone. Fans of the COMIC want one.
New issue numbers have a tough time climbing because modern readers want new comics. Seriously, look at how many moderns are at 20 issues or LESS. People abandon books for new books. Publishers are rebooting and renumbering all the time. Independent creators start new comics... etc... However, Invincible has maintained readership for over 100 issues and in my opinion keeps getting better as it goes.
It needs more word of mouth. Your Facebook page is perfect. The compendiums to catch up are perfect. Making announcements about Invincible at cons is great. I think they are doing the right things. I think the future is bright for Invincible, we just need to keep telling other readers how cool the comic is. For example, my secret santa boardie wanted Spider-Man comics, so I gave him some Spidey books but also added an Invincible Vol. 1 HC and told him how much I enjoyed the comic and he should give it a try. Bumping this thread to talk about the current issue is great. Stuff like that. (thumbs u
I've been trying to get three people to read this book, but they are hard-headed.
