Today, when I opened Google, I found the Google’s logo had been?changed as “Edvard Munch’s Birthday”, so that I found myself is very lack of art knowledge. I don’t know who?was E. Munch. I clicked the Google’s logo, titiled as? “Edvard Munch’s Birthday”, It went to search page, htere waer a lot of results about E. Munch. There is an introduction to E. Munch, if you want to read.
