Beer 2

It is clear that the artist thoroughly studied his subject.
He could have contented himself with a static display (remember Wiel's), but he did much better. The surface moves under the right amount of froth (except if you are British). The liquid comes down with lots of air bubbles.
Waterdrops form on the cool outside of the glass. The bottle and the beer cast their shadow on the wall. And, before you pity the poor folks on the top floor for loosing their views, you must realise that even the windows are painted. The ornaments of the façade are continued in paint on the side-wall.

Nobody could possibly improve this one. The Art of painted advertisements culminates exactly here.
