Art Nouveau store front in Brussels: Paul Ankar, I actually know this flower shop, it's not far from the Parc in central Brussels. The flowers are really nice as well - Daniel Ost is quite a famous florist.
“ Flower-shop, Brussels, designed by Paul Hankar, XIX century. ” This is literally the perfect, most fitting sort of thing to put in the window of an Art Nouveau front like this. One of the things I enjoyed about Brussels was the Art Nouveau.
