I have planned to photograph this wall for some time now, and now when I had the possibility I took it. Unfortunately it was snowing a bit, so there are some white artifacts (snow flakes!) in the picture.
Colors and perspective are fixed in GIMP to improve the image.
In the painting you can see an old man, standing or kneeling in the field of flowers, holding his hat, in a position which makes me think that man is in grief. The blue serpent is laughing behind the man and has its tail around old man's arm.

The same wall used to have "Pepsi" wall painting on it. The old painting can be still seen from Google maps.
