I was going to say Kickstarter... but there's several other crowdfunding options these days, so whatever works for the publishers :P
I've seen plenty of good campaigns that probably didn't need their own threads, so I'm (and others welcome to do so also) going to start dumping links to good looking ones in here for like minded fans.
I'll start it off with, this one:
The X-Men Art of Andy Kubert
There's a bunch of other add-ons and things like stickers, pins, posters and of course, various tiers and options for the book.
