>>109437951The early original Brave and the Bold was random team-ups. Lots of first appearances of DC concepts in it.
Then, around issue 67 of the original series, it swapped to be a Batman + Guest team-up book.
It ran until #200 like that, with often really silly stories (in ran during the Batman '66 TV show after all).
The last time they tried an ongoing in the late 2000s it was mostly random team-ups. The first couple had an ongoing story to them though.
