We had a 1,000 piece puzzle going and were at least 2/3rds done. We did the main picture part and was left with the just lightly shaded green background. Unfortunately there was one very noticeable piece missing and rather than spend the next 4 days struggling to finish it with the empty spot we tossed it the recycle bin.
So we did this 300 piece one instead. In the second photo you can see what Captain Merrill Stubing did after he retired from Princess Cruises.
