I would bet all 15,000 will not be destroyed. Someone involved in the process will keep some, with the idea of making $$$ sometime in future, due to the controversy.
Probably true. Also, I'm surprised that the manufacturer did have the ballclub proof the work first. Usually on an order this size, you think you would want the client to see a proof copy of the work first before having them sign off on such a large production run.
There was definitely some incompetence involved here.
