There's a comment about the CG Conn display: "It is safe to say that no musical exhibit at the World's Fair attracted more universal attention than that of C. G. Conn, and the case in which this exhibit was contained cost $1, 000; the exhibit itself was valued at $12,000." Inflation Calculator time. $12,000 is $332,267.49 in today's money. These Exhibitions used to be a really, really big deal.
