My Dad had started doing a puzzle of the Avro Arrow at Easter when I was home. My sister Karen and I helped him out with the plane and the border. When we left, he said we had left him the hardest part.
At the time of his passing, the puzzle still was unfinished. We just couldn't leave it that way or simply put it back in the box so we decided to finish it for him. All my sisters, brother-in-laws, nieces and nephews had a hand in completing the puzzle for Dad.
