Bit of a cliche, the first one, but I love it: (Van Gogh, Starry Night)
The second I saw on a gift card, and really liked it. Internet helped me to track down (it was uncredited, oddly, on the card). It's Flaming June by Lord Frederick Leighton... which also (I believe) inspired Paul Weller's "You do something to me". Seeing as that's a fave song of mine, it all fits together neatly.
