Interesting discussion.... The seller actually advertised the film being in the the film was part of the deal. It actually made it more valuable to me as otherwise I'd have to purchase 620 reels.
i actually contacted the seller the I had images but never heard back. I would happily send the jpegs to her. The fact that the law is so different in Germany shows that you needs to know your country's laws. My guess is she has no attachment to the images...probably bought the camera at a thrift shop or garage sale to resell on Etzy.
