I was reading Giffen Justice League International issues right around the issue # when JL Europe debuted, but it doesn't look like they announced a new team being formed in Europe within the stories in JLI. So was it just done through house ads that "hey we're starting a spin off series in Europe", and thats the only way readers knew?
Thought there would be some mention of it in one of the issues, or even on the last page of an issue like "coming in May, Justice League Europe!" or something like that.
Did I miss that?
