Decided to finally dive into this monster last night. Finished volume one, which contains Justice League 21-22, 29-30, 37-38 and 46-47. I'm sure I've read all of these in various reprints over the years, but I am determined to read this boxed set straight through, cover to cover, in order, so it gives these various Crisis stories greater context. Look, these are silver age DC's. They're pretty corny. BUT, they're also charming and colorful, and Gardner Fox always had imaginative ideas. The pinnacle of superhero writing? Dear me, no. But a colorful trip down nostalgia lane nonetheless.
I think this puts my total up to 17 for 2020, not counting the Mickey Mouse strips books I've been reading lately.
