These are records of the bonds that George purchased during 1916. Some $171,000 worth. His results appear to be mixed, but just the sheer scale of the purchase is impressive. Online sources list the average income for the decade of 1910-1919 as around $750. Which puts these purchases at about 228 times. Scaling that up to today's average income of $57,300 in 2000, this would be over $13 Million.
