I just watched Chapter 7 of Genius: Picasso on NatGeo, and it said that in 1912 "Pablo's Family of Saltimbanques becomes the most expensive painting in history, selling for 12,650 francs."
The episode implied that that was a huge amount of money, and I'm curious to put it into perspective in modern life to get a sense of it for myself.

Here is how I've attempted to calculate the equivalent:
WolframAlpha says that 1 USD in 1912 is equivalent to 26.72 USD in 2018 because of inflation. (And OfficialData.org says "$1 in 1912 → $25.03 in 2018", so $26 seems like a reasonable estimate.)
That's a helpful starting point, so then the question is "What was the exchange rate between FRF and USD in 1912?"
says:
1 French franc [1795-1960] in year 1912 could buy 0.2904245694156011 gram gold. The price of 0.2904245694156011 gram gold in year 1912 was 0.19280860722030124 US dollar [1791-2015].
But since that site is labeled "(test version 1.0)" and the way that that site pulls in data with date ranges leads me to believe that it's imprecise.
Any suggestions?
