Mickey Tettleton had that batting stance where he'd start with bat relaxed and pointed toward the catcher... (he'd come to a more traditional position as he timed the pitch and started his stride)
Opposite extreme from that time was Julio Franco
his bat was also parallel to the ground, but he'd point the barrel-end the opposite way toward the pitcher...
I wonder if kids today can mimic and identify all the stances like we could?
