puzzled

Slow Sunday recovering from last night's wine intake. We made some progress on the Robert Crumb puzzle. It's probably the most difficult puzzle we've ever had. There is a huge area of shades of white which I think we will just need to brute-force. It also isn't helped by the fact that the picture on the box is not the same crop as the puzzle. Since I have taken this picture we have made some progress but we essentially have mostly a pile of blue/white puzzle pieces left.
