A Biggie freestyle from 1991. He was only 18, and his flow was just as dope as we knew him from later on! This was video taped by one lucky dude outside a corner shop in NY. Video:

It surfaced in 2008, 20 years later, and a year before the Notorious biopic, which included a remake of the song called Guaranteed Raw. The man Biggie was battling is called Supreme and sources have stated over 5 battles like this have taken place between the two.

Additional footage from the same block party has surfaced where Big can be seen in the background:
