Click on the photo to enlarge it. You will see the price of prints. This was in the pre-color film days, so the cost of the print would double if you wanted it hand-tinted to colorize the print.
The interesting thing is that the prices are about the same for prints in 1959 as they are now -- from around 35 to fifty cents each. This makes photography back then quite expensive, as 50 cents could buy you a pound or two of hamburger.
