Backer board Spidey by Sam de la Rosa

I was going through my comics preparatory to selling off most of them. I had pulled out some bad looking bags & boards & was about to throw them away when I noticed this piece on thee opposite side of a backer board. No idea when I got it. Back in the 1990's I did a ton of events with Sam, sometimes at conventions & sometimes at our store. Somehow I never got a sketch from him in one of my sketchbooks, so I was happy to find this.
