As a fan of comics it is good to see the big two Marvel and DC publishing collected volumes of back issues. Yes I admit they are only available in black and white, but when you're getting over 500 pages in one volume it's hard to argue with the value. Also some of the artwork looks amazing in black and white anyway!
These collected volumes are a great way of catching up on the backstory of your favourite characters, or discovering some new ones. Keep an eye out and see what you can find.
