Two sets. Everything in the photos is included. The instruction manual for 60193 is missing page 1. The minifigure for the saber-toothed tiger from 60193 is missing. I built it while looking at the instructions. The airplane parts are mostly complete. Some parts are missing from the buildings in both series. Some parts have been substituted with different parts, and there are some missing parts. Please purchase only if you understand that these are used items.
