Making products from vintage magazine photos
However, determining whether certain photos are in the "public domain" is not as straightforward as you might think. It depends when the photo was originally published, where it was published and whether the copyright holders properly renewed the copyright rights when the terms came up for renewal.
It is possible that the magazines may still be entitled to the copyright rights on the photos, in which case you would need permission from the magazine to use them. Best to speak to an intellectual property to map out your strategy for using them.
