This is a first for me. You keep looking at them, then look again, and then even when you look again you find something new. Who put this Pioneer Jupiter Satellite stamp on the Apollo-Soyuz FDC. The stamp is tied to the cover with the cancellation and the FDC clearly states that it should have a pair of stamps on it for the Apollo Soyuz. Maybe this is the only error out of billions. Maybe I am rich now. Maybe I can go on vacation now. Anybody have more examples of this type of thing? or comments? - Jeff
