Query: Mostly about models from pre 70's era

I thought this book would focus heavily on models of the 80's and 90's, but it's actually more like a history of modeling. Much of the book seemed to center on modeling/models from the 50's. These figures weren't familiar to me and I wasn't interested, so the book felt like a waste. I was kinda of shocked because the author was so ubiquitous as a go-to authority on modeling during the 90's. When TV tabloid shows needed to interview someone about models, they'd go to him.
