Interchange by Willem de Kooning was sold for $300 million in 2015, how much was it originally sold for?

"Interchange", also known as "Interchanged", is an oil on canvas painting by the Dutch-American abstract expressionist painter Willem de Kooning (1904–1997). It measures 200.7 by 175.3 centimetres (79.0 by 69.0 in) and was completed in 1955. It was one of de Kooning's first abstract landscapes and marked a change in his style under the influence of fellow artist Franz Kline. In September 2015, it was sold by the David Geffen Foundation to Kenneth C. Griffin for $300 million (equivalent to $325,731,065.70 as of 2019), a new mark for highest ever price for a painting at the time.

De Kooning sold the painting shortly after it was completed. It was bought for $4,000 by the architect Edgar Kaufmann Jr., whose father Edgar J. Kaufmann owned Kaufmann's department store in Pittsburgh. Kauffman's estate sold the painting alongside other pieces of his art collection at Sotheby's in New York in November 1989, where it was bought by Japanese art dealer Shigeki Kameyama, owner of the Mountain Tortoise Gallery in Tokyo, for $20.7 million, setting a record price for a living artist (since surpassed).
