While this has some interest, the length and style mean it’s really for collectors only.
Ironside was a Scottish wrestler, so this has some good insight into some of the names and characters who didn’t get the TV exposure. It’s more of a collection of stories and reminiscences than a chronological career history.
Unfortunately it’s only 88 pages so is likely a single-sitting read. It’s also written with kayfabe in full effect, which won’t be to everyone’s taste.
