I love the combination of the wine and the saxophone in this poster. This is a great example of a minimalist design with a double meaning. The saxophone represents the "Jazz & Blues" and the Pouring wine represents the winery where the even is being held.
Halftone has been applied to the image - model, cityscape, lightbulb and whirl. Green, teal and black. Simple and basic application of text information. The logo doesn& take way from the poster, it remains quite subtle but in the same breath important.
