Chocks away

We bought this jigsaw in the summer when I had a day off work to go to hospital and after my visit we went to the Milestones museum in town for their Lego special. We normally do jigsaws over Xmas/New Year as there is nothing on TV and we are at home. This one is positively evil, there is no shade or pattern to the white background, and as you can see once we had completed the drawing and text it has become almost impossible to do the rest...
