This is an excellent collection. I started Justice League in the 70's, when Dick Dillin was the artist, i loved the book. Unfortunately the "Crisis of Infinite Earths" removed these stories from continuity.
That’s when i started,Dillon and Len Wein were my gateway book to the Justice League of America.My first issue was #111 with the Injustice gang.Awesome issue with 100 glorious pages for a measly 60 cents!!
