This is a vintage Boeing S-IC Thrust Structure diagram drawing schematics. It is dated 1966. It has been folded and stored for years and it has yellowing on it in various places as shown. It is very large. This is in good overall condition but it does have some flaws. It has the yellowing, some creasing and maybe some small tears. You get the actual item pictured so please look at all photos and ask any questions before purchasing. THIS WILL BE SHIPPED ROLLED UP IN A TUBE.
