Canvas is an 8"x10" and the poster is on a 5"x7" board. I've always been drawn to the covered jars and jugs in the work of eighteenth century painters. Not really sure what the covering was for. Can't imagine it doing much besides keeping out bugs. It couldn't really have worked as a preservative. The hardest part was tying the little string around the mouth of the jug in a bow knot. I had to use a rubber band to hold it in place. It always amazes me how little info is needed in the poster study to give it a sense of reality. That coherence has to carry over to the finished piece or all the detail in the world won't save it.
