"We built this set in 2 sessions, one way 4 hours and the next day 3 hours. The build was fun and engaging. It was so much fun seeing each bag add more to the scene. I was 10 when it came out so my memories are from my children and seeing episodes through the years. The detail is spot on. I only have 1 criticism with the instruction book. The page background is black and some of the pieces are dark Brown, dark blue and black so it can be difficult to see. My wife and I enjoyed building Sesame Street and look forward to playing with it!"
