Today, my topic is indentity and copyright, rather than Hamlet's existential dilemma.
What happens when two creators (authors, photographers, painters) have the same name? In the case of a father and son, a tag might be added, as in the case of Pieter Brueghel The Elder, and Pieter Brueghel the Younger.
Suppose two artists are not related, but have almost the same name, and one is far more talented in the eyes of the art world and also --perhaps-- rejoices in an unimpeachable reputation. An owner of a work by the obscure painter might wish very much that the signed work he has is a valuable early work by the famous author of the same name. (I hesitate to use "namesake" because that usually implies that the one was intentionally named in honor of the other.)
All the best,
