Usage notes

Most senses of the terms master copy and mastercopy have the semantic notion of "the copy that is the master version", but the fine arts sense of the terms instead has the semantic notion of "a copy of the master version". This sense difference puts the pair into the class of contranyms, albeit it a little-used example of that class.
