I want to know the answer to the following question:
How did James Gamble Rogers faux age the windows?
All the background I'm provided with is that "Many of Yale's buildings were constructed in the Collegiate Gothic architecture style from 1917 to 1931, financed largely by Edward S. Harkness Stone sculpture built into the walls of the buildings portray contemporary college personalities such as a writer, an athlete, a tea-drinking socialite, and a student who has fallen asleep while reading.". Is that enough to answer the question?
Answer: no
