Description

THE PICTURES ARE PART OF THE DESCRIPTION SO LOOK CAREFULLY
Here is a nice old dual sided wood interlocking jigsaw puzzle from J K Strauss with one titled "WHAT A BEAUTIFUL MORNING" and the other "THE WHITE HOUSE" that is complete in the original box.  This puzzle has printing on both sides so starting them all on the same scene adds some complexity to the build. The puzzle has 300 pieces and has been gently used and looks like the pictures shown.
PLEASE LOOK AT THE PICTURES AND ASK ANY QUESTIONS BEFORE YOU BID THANKS
I know a little about a lot of different things but I am not an expert on anything and do the best of my ability to show the condition of these items.  If you are an expert on something I am selling and know this spring is always missing or that part is always cracked please let me know before you bid because it doesn't help either of us to not share right?
