The picture is a painting called Whites Head Passage by Harrison Bird Brown. It is in the permanent collection of the Portland Museum of Art. Brown is one of my favorite artists from the late 19th century.
i agree with the comment about the font. also, i think the colors a bit 'all over the place'. i would try to coordinate the text and background colors with the painting. it is a beautiful painting, and makes for a classy beer label imo
