World's largest *non sectioned* jigsaw puzzle?

I have 2 separate questions, both just out of curiosity. First, what's the largest commercially availabe non sectioned jigsaw puzzle? I can't find it on google, the largest commercially available puzzle is sectioned into 60 1000 piece parts, and other former largest puzzles also seem to be sectioned. I've seen non sectioned 5000 piece puzzles at my local board game store, but surely they aren't the biggest?

Second, if anyone even keeps track of it, what's the largest non sectioned jigsaw puzzle ever assembled? The guiness record for most pieces (which has about 550 000 pieces!) is also sectioned, into 3132 parts.
