The cardstock I'm using is actually posterboard, I believe, because of it's size, thickness, and finish. The reverse surface is just mill finish, but the obverse surface has a pearl finish--that I've already done a paint test on.

I don't remember where I got the posterboard from--possibly Blick Artist's Supply in Downer's Grove, IL. I've had this single sheet for many years.

Here's the label from the corner.
