By my understanding, copyright law would generally interpreted as allowing someone who buys e.g. a book containing some copyrighted poetry, to use the works personally in a variety of ways including, e.g. incorporating them into an embroidery piece intended for display in their home. If it were well known that one publisher did not object to such usage, but some other publisher would seek to punish anyone using their work in such fashion, revenue from the additional sales made by the first publisher as a consequence of this would likely exceed any revenues the second might plausibly achieve from selling countless individual licenses to produce one-off works.
What rules would apply if the person who embroidered the work became famous, and the value of the work as e.g. "A piece of embroidery by ___" vastly exceeds its value as "A copy of the poem ___", and the work would become part of an estate sale or bankruptcy liquidation? Would the publisher of the poem be entitled to any additional revenue at that time? How much? What rules would apply to e.g. published retrospectives of the works embroidered by the person? It would seem fair that if a publisher mass-produces copies of a book containing a photograph of an embroidery piece in which the entire poem is legible, the author of the poem should receive some sort of payment, but it would not seem fair for the author to require that the publisher either pay $1 million per copy of the book or else exclude the work in question from it.
Things would of course be simplest if the person who produced the original embroidery piece had nogotiated a license that provided for the possibility that the embroidered work might become notable for reasons other than the poetry contained thereon. Of course, the practicality of having everyone who embroiders poetry negotiate such a license would be essentially nil.
Is there any accepted practice of assessing royalties based upon the established value of per-copy royalties of the work or publications containing it, or how are such things handled?
