A little puzzle

Doing a quick internet search for a board game my heroine might play, I got distracted (my perennial problem) and found this site where I can make a puzzle:  To play, click here.

It took me longer than I thought — it’s tricky —and they didn’t even have jigsaw puzzles in her time so there’s no excuse for the time I spent playing around with it. But be warned, some pieces are hidden under others and also at first I thought the two separate groups of pieces were duplicates or some techie thing I didn’t get. But they all count.
Have fun.
