They look nice from the outside, but how easy are they to read? just from that Dandy link, looking at it open to the Corporal Clott pages, there are whole panels on the right hand page that are hardly visible...maybe it'd be easier if you had it in front of you, but i'm not sure.
I suppose if you're just collecting the issues to have them, it'd look nice on a bookshelf (and it really looks smart), but i like to read my old issues, and i'm not sure how easy that would be. Maybe less comics to one volume would be more managable too.
