This is the scenario that concerns me. I sell a fine art print of a public domain work on a site like Amazon, using a photograph that originated from the museum that owns the piece (such as those currently available on WIkipedia). According to Bridgeman vs Corel, photographs of two-dimensional works of art produced solely for documentary purposes are not protected by copyright, if the subject work is in the public domain. However, as this is not settled law, many museums still claim ownership and expect you to license.
If Amazon (or other retailer) receives DMCA complaints about these products, my account could be suspended, severely damaging my business. In that case, I would need the DMCA complaint withdrawn in order to resume business. What are my legal options here?
