Back in the 70's I was travelling with a friend in the SF Bay area, We met this photographer who had a shot of then candidate Jimmy Carter holding up a street sign that read "end Ford Begin Carter." Carter asked if he could get an enlargment of it. He wanted it for a big press event. So this guy makes a 24x30, mounts it (I saw it it was a great shot) and gives it to Carter's campaign people. The event happens and is on all the news etc, but this guy's blow is nowhere to be seen. It turns out someone had leaned it face down against a wall and when it came time to show it off no one could find it. I understand it was also visable, back side only, in some stills from the event .
I have far too many missed opertunities and not enough time to relate them.
