Justice League of America No.135 "Crisis in Eternity."
Justice League of America No.136 "Crisis on Earth-S."
Justice League of America No.137 "Crisis in Tomorrow."
All three sections first appeared in Australia in the one comic,
Super Adventure Album No.8 shown above.
I loved this one as the Fawcett heroes really appealed to me.  Mr Scarlet & Pinky seemed almost surreal, whilst Bulletman & Bulletgirl intrigued me.
Throw in the Earth-Two Batman & Robin in their only Silver Age JSA adventure and you have a real winner.
