being in the printing business now i understand that stated # of copies is usually correct, except for overpintings to make up for the spoiled copies that did not make it past QA or to have a buffer to protect from any other evens that could lead to the destruction of the original print run.
so yeah, 1k is probably close, but with overprinting, it probably came out to 1100 or 1200. larry may have received 1k, but there are additional copies out there that the printer would have made to make the order requirement in case of unforseen circumstances. a buyer would be stupid to not have some type of overprint on their title because that will take away from their profit potential.
