Comic collection

If you wish to start collecting comics, trade Paperbacks, which some people call "graphic novels" are considered to be your best option .

These graphic novels  collect full story-arcs from the original comics in a full book format. Usually between 3 and 12 individual comic issues make up one trade paperback.

They are also almost always cheaper than tracking down and buying the individual issues of a particular series.

Collecting comics to make money is no longer very profitable and most collectible ones are expensive.

The Batman series is popular starting point.
