This book actually does dive into some of the older years of queer history, the 20s-60s iirc. Mostly centers on the 1950s, but it's actually a very interesting book. Some of the landmarks are still around! None have placards indicating their importance to gay history IRL, which is a bit bittersweet when you look at all the other placards of other historic moments in history at the same location.
