Three works of art

I took a walk in the Old Town earlier in the week. It was very cold. Freezing. And not too many people out and about. Perfectly understandable. Most visitors probably checked out a museum or two. I found a few paintings during my walk. Top photo shows how the Polish illustrator and artist Magda Korotynska see the Old Town. You can buy a poster for 150SEK. Spotted outside a store at Västerlånggatan. I don't have any info about the other paintings, although the third one shows a building at Mariaberget on Södermalm. I found them at three different stores.
