1) I have a 1950's children's book from the UK that lists the publisher and I have researched this publisher and haven't found any trace of it. How do I get permission to use an image from this book in good faith? I want to put it in a video I'm going to sell.
I suppose my bottom line question is at what point along the way can I consider having "done enough" and still use the image?
2)I have some old 1930's/40's Valentines Cards that I want to use in the same video. There is no mark, manufacturer, copyright symbol etc to guide me as to where to get permission. The same question exists for these images, at what point can I consider having "done enough" and still use the Valentines.
Thanks for your guidance.
