Rare Milton Bradley 3000 piece puzzle

This is the one of the hardest, rare Milton Bradley 3000 piece puzzles I have ever done. I was unable to finish the sky. But it’s a fun, vibrant colorful puzzle. With a bit of the sky to go at the end, I had not found any missing pieces in the entire picture. So, I assume it is complete. I only see it listed as a 1000/2000 piece puzzle online, going for over $60. Brought it with me from Europe.
