It's a stick man walkin while puffin a joint. Also has a smoke cloud overhead.
It is actually a "tag" from a legendary "old school" graffiti artist from NYC. I use his moniker on here cuz it fits so well.
If u google Stay High 149 under images u will find a ton of his stuff.
BIG Respect to the original (not me) Stay High 149, the Voice of the Ghetto
