Double sided pieces (there is a picture on both sides of each of the pieces; so you can see the interior and exterior of the chapel).
100% complete and poster included.
I can meet you in London the next time I'm there.
Also available: 3D Sistine Chapel with one missing piece (at the back on the base). This piece has been replaced with a substitute piece (if you didn't know it was missing, you wouldn't likely notice it due to its location. Also does not include the bonus poster. Available for $40 (the last picture in the ad shows the "replacement" piece).
