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.
Another design that really catches my eye is the use of creating an object without outlines. The shape is basically created from the background like the water colors on this one. Designs like this could be helpful for packaging or even specialty cards
