I had this piece of cardboard sitting in the back of my van, sealed in a plastic bag. As I recall, it came with the last set of Picks that I bought (I need to buy more- maybe I will make another bookmark when I get them).
I stumbled upon the cardboard by accident some time after I'd already broken the first pick; and Immediately my brain was like, this NEEDS to be a bookmark, but it would be a little bit until I realized what needed to be ON the bookmark-

I was working on The Thing That I am Calling DaFuq (until I know what DaFuq it is) and there is an image not unlike this somewhere in the 4th decade of pages; and I thought- this is perfect.
This will be my bookmark.
