Im not sure of a collaboration (that would be super dope) but I do know that girl is sending out a bunch of the wooden OG dolls to skate shops that have been supporting them since day one and allowing to put whatever they please on it as art.well the head of the girl doll has a Supreme S on it (looks like the same font anyways) and it looks to have a shibuya bullet hole on it. So it is very probable. for anyone that doesnt know what I mean by the girl doll its one of these:
Turned on my Csi shit today. Dude from supny posted this pic on his instagram. He hashtagged SupremeNy and was talking about 20 years of girl skateboards. Could be nothing but could be a lead on a possible collab and I didnt even realize its Girl's 20th.
