That is a real nasty, getting the tape stuck to a bit of the comic, which this method should avoid. I've been sliding comics in and out of bags for so long that I sometimes get a bit careless and, only at the last minute save the day, or the cover. Not quite on the same topic, it seems to me that, historically, comics were bagged with the flap at the top, but in the last decade, some dealers here insert the comic upside down and apply 3 pieces of tape to the flap which is, obviously, at the bottom. This way was pioneered in Scotland by the late, great and sadly missed, Pete Root, dealer supreme. As I am old and stubborn, I have stayed with the tape at the top. None of this is really that important but still causes arguments between folk who are converts to the Root method and the few who still use the old way. For anyone who is a bit unsure, always use magic tape, especially for your own comics. You've no idea how British comics often come bagged. Bakers' bags, indeed !
