I played with Ravensburger board games and puzzles growing up. We lived in Berlin for a few years, so quality European toys were easy to come by.
I knew I was getting a well-constructed puzzle when I purchased this super-sized 24 piece jigsaw puzzle for Z for her third birthday. And indeed, the pieces are large, sturdy and easy to wipe clean. It's been such I hit I used the $10 birthday certificate our neighborhood toy store sent her to purchase two more puzzles (another 24 piece one for now and a surprise 36 piece puzzle for later).
Z doesn't get tired of putting them together, and each time she opens the box she needs less and less parental guidance. Which is almost too bad, because while I get sick of reciting my lines in "pretend you're the big sister and I'm the mommy," I kind of enjoy putting together puzzles!
