I bought this puzzle from a house that had a dog, and apparently the dog got a hold of some of the pieces so there are a few with bite marks.  

This puzzle is from 1963, and despite the few issues, it is in overall very good condition to be 60 years old. 

See all photos.  I worked this puzzle, it is complete.

Non-smoking, and from my pet free home, although it was purchased from a home with a dog.
