Intellectual property refulsal
I'm trying to get a better understanding of what is and is not acceptable for commercial use, particularly when it comes to intellectual property. These 3 images were rejected yesterday and I'm not sure why. I can't find any logos or company names in any of them. The bridge is well over 120 years old and is not in the "known image restriction file" nor can I find anything online that would indicate a property release would be necessary. Any help would be greatly appreciated.
