The tiles are in fine condition. The trays for the tiles are in poor condition as is the 1981-82 rules card. The 4 racks are new, all yellow and still shrinkwrapped. (I sold the original 5 racks that came with this set separately)

I'm not sure what the tiles are made of. Google says by the late 40's Catalin and Bakelite production ended. 

This set was made for the Chinese rules so there are 8 seasons and no flowers. There are 8 jokers.
