I designed the NASA's logo that was done with bent one line for each letter of "N", "A", "S", "A" that had been retired thankfully. I didn't receive any compensation for it. I just gave it away. I was hoping I would garner some name recognition but it didn't quite turn out that way. I was in a very delicate situation back in 1979 and early 1980s.
I also designed the logo for intel. One with letter "e" dropping about half way. I was hoping to get paid but at the last minute this woman who set up the meeting for both of us, I and the man from intel, intervened and mangled the deal. I had gotten nothing out of that to my dismay.
