I thought I had it figured out Chris. I was the owner before him. I found the sign decaying in the back yard of a guy on L.I.
If you'd like me to fill in the blanks for you from the time it came off the wall, I can. Just contact me privately.
You seem to be a great guy with a serious interest (and history) in Motion cars. I'm glad it's with you. That's where it belongs!!! I have a lot of photos of it as it was recovered, before the previous owner spent a lot of time and money bringing it back to it's glory!
Just imagine......the only original remaining sign from MOTION! Is that

or what????
