What were the first jigsaw puzzles made of?

Misnomer or not, jigsaw implied wood

We have an old wooden jigsaw puzzle that I used to play with in my youth. A nice durable piece that was passed to my mother, to me, to my son & hopefully for generations to come.

TestyAlien3443, I love jigsaw puzzles. I have 10 that I do, take apart, and do again. Great way to pass time while listening to music.

60000 pieces takes a long time!!

And now you can do them digitally.
