Aye, you're right, I should just use the biggest bag and fold it around but I'm a bit fussy and like a nice fitting, unfolded bag. Just me. I actually enjoy bagging comics and I can listen to music or radio plays while getting it done. But, the smell of newsprint, sort of vinegary, how evocative and pleasing and something you don't get with modern comics.
As for Rozakis and his opinion, many years ago, when DC started bagging comics in those flimsy, sealed bags, trying cynically to create a collectors market, a senior DC exec. (who shall remain nameless) told me that some collectors would keep the bags sealed and the plastic would rot or melt away in a year or two and could ruin the comic.
He was wrong, by the way. I saw one of them in a shop recently and the original bag was a bit crinkly but intact. Don't know what it was doing for the newsprint though.
Thanks for the link.
