Somebody might go into Wikipedia and change it.
Jan Matulka (7 November 1890 – 25 June 1972) was a Czech-American modern artist originally from Bohemia. Matulka’s style ranged from Abstract expressionism to landscapes, sometimes in the same day.
I was looking up Matulka because of his “Autumn Landscape” (featured as the cover art of Into The Great Wide Open), which I increasingly like, the more I look at it. Which is probably why Tom Petty and the Heartbreakers picked it as the cover art.
It turns out that “sometimes in the same day” has been in the article since it was first created.
