The Barber is a rather small art gallery, but they have an impressive collection.
Quoted from their website: "Among the artists represented are Bellini, Botticelli, Holbein, Veronese, Stom, Baschenis, Rubens, Van Dyck, Rembrandt, Poussin, Gainsborough, Turner, Delacroix, Ingres, Rossetti, Whistler, Manet, Degas, Monet, van Gogh, Rodin, Gauguin, Picasso, Matisse, Magritte, and Schiele."
I mean, an original van Gogh right there on the wall. It's not hidden behind glass or anything.
And there is no entry fee. If you spend much time at all around Birmingham, then you have to be a philistine not to go.
