Good news! The jigsaw was completed this evening, all pieces were there, with one extra piece from another jigsaw to add to the fun, and the wonderful box has been repacked in the parcel in which I received it, and addressed to Peter, who will presumably finish it much faster than me (almost 6 months!).
June, thank you for a great puzzle, which I thoroughly enjoyed (often during very late night hours) -- and thanks also to Alan Kirby and Alan Snelson for making the picture available and preparing it for the jigsaw. An excellent jigsaw picture, and very sharp too -- well chosen and prepared.
Wishing all those who try it next, as much fun as I had

.
Looking forward to the next jigsaw already -- later in the year would be great.
