Some people collect stamps, some prefer to go for the more estoeric and collect empty heroin bags. Personally I've always found branding of illegal drugs fascinating. I don't know much about the powder drugs but I remember buying ounces of hash in the 60s that was packaged in muslin sacks with printed logos. As I recall my all time favorite was the Red Lady. That was some good hash. A thick reddish brick that resembled sandstone and crumbled up really easily.
So I can relate to Clayton Patterson's attraction to the smack bags and appreciate that he's preserving a little bit of history that might otherwise go unchronicled. I hope he manages to put together the book. Not that I would buy it necessarily, but I wouldn't mind having a look at it.
