Speech bubble printed on regular printer paper, cut out, and carefully affixed to the page with nothing fancier than sellotape. A crude fix, but workable. The book couldn’t have been preserved in its pristine condition anyway and better a slightly blemished but readable page than a pretty page with a piece of the story missing.
Bloody good thing I’m not a proper collector.
