Possibly-flown: representatives manning NASA's booth were split as to whether the patches they were distributing were flown or were from "flown missions." As collectors know, even if they did fly, without any writing to that affect they might as well have never taken the trip.

As noted earlier, cosmonaut Dimitru Prunariu visited our booth. He returned today to deliver a stack of his signed portraits and provide us with a few of these commemorative medallions issued by the Romanian Space Agency. Look for these to appear soon on buySPACE.
