I can't find any other detiel of this painting...
2 . Jean-Honore Frangonard--Le baiser à la dérobée(The Stolen Kiss), St Petersbourd45x55, 1766, Musée de l’Ermitage
It's a very famous oil painting by French painter Frangonard.We can find many books and articles write about it.
3. Romeo and Juliet
4. Francesco Hayez(Italian painter)--L'ultimo bacio dato a Giulietta da Romeo(The Last Kiss of Romeo and Juliet)
5. Ford Madox Brown(English painter)---Romeo and Julie,1870
6. Francesco Hayez--l bacio(The Kiss)1859),Pinacoteca di Brera, Milano
Naturally,it isn't a really bad idea for put some mystery and remarkable paintings in the begging of a movie,but the quality and mean of those paintings is very important.....
PS: I love two other paintings which are considered singulier and famous by some studise.
1. Jean-Honore Fragonard--Le Verrou(The Bolt)
2. Sandro Botticelli--La Nascita di Venere1485. Galerie des Offices, Florence
