Cost to produce photodrama of creation

Have you ever wondered how much it cost to produce the Photodrama of Creation? Wonder no more. From the "Divine Purpose" book page 57.
"At least twenty complete sets in four parts were prepared, making it possible to serve eighty cities each day. And it was shown at a cost to the congregations of between $150,000 to $200,000 for 1914 alone."
How much would that cost today. be ready. $6,134,920, over 6 million dollars. What did Brother Russell say after the project was done and the bills had to be paid. Again, on page 57.
"God kindly veiled our eyes as respects the amount of labor connected with the DRAMA. Had we foreknown the cost of time and money and patience necessary for the start we would never have begun it. But neither did we know in advance the great success that would attend the DRAMA."
