It really depends on how it's used...I've got an awesome one for my two volume Wolverine: Origins bind that has Logan's face with the Canadian flag painted on his face...but I'm only doing the small portion of the spine.

I think a 20-volume set of X-Men comics in graphic bound HCs with this on the spines would be pretty damn epic. I may have to buy a run of 500 old x-men comics so I can do this...

I was kind of planning on using this one myself...I don't know how many volumes it would take though...I wanted to use it for the Heroic Age portion of the X-Men (after Second Coming to right before Schism).
