This is a Moleskine sketchbook that I had a friend laser engrave. The SCF stands for "SketchUp Community Forum". I drew inside the front and back panel then I drew the first spread. Then it was off to another member of the forum, or anyone else. To date I have no idea where it is or how many drawings are in it. It could be at the bottom of a ravine for all I know. I just hope someday it shows up in my mailbox full of dents, dust and drawings.
