Unfortunately the owner was an old school guy and had neither system on the museum. I understand other places around possibly had cameras that may have caught something.
I was told a large brown truck was seen near the museum ( which is in the middle of nowhere and has almost no traffic). This seems like it was a professional operation as the signs were very large and there was 20-30 signs.
I have had a call this mystery seller with the restricted number also had john deere signs.
