Thank you both for the responses. You can see the page in question here. This is not a piece with any historical significance, just one from a favorite GL story.
You can see tape in multiple places, and I know from other pieces that this was done on multiple pages in the storyline. It’s original, which is interesting from a process perspective, but also means it’s been there for about 21 years now.
My concern is not so much about presentation as preservation. It’s not an expensive piece, but I would hate to buy it, let the tape sit, and have irreparable damage done to a great page. It’s not something I would probably try to remove myself (unless it’s just barely hanging on), but I am interested to know what long term effects can be expected from late-‘90s scotch tape on comic art. Maybe they make it better than they used to. Tape/adhesives are not in my realm of expertise.
