Bob creates a doll of Rob (with startlingly realistic resemblance) without him knowing and starts selling it. Bob does not promote any idea, service or other product with this doll: it's the doll itself that is being promoted, so there's nothing for Rob to endorse (or refuse endorsing).
Does Rob have any legal standing to stop Bob from doing it?
Let's assume that 1) Rob is no one (not generally recognisable in public); 2) He is a celebrity or a politician.
If Bob is to encounter any legal troubles, why exactly? How making dolls is different from selling photographs of Rob taken in public without promoting any product, service or idea — which in most common law jurisdictions would not require Rob's permission?
