The typography on this invitation draws me, especially the difference between normal, bold, and italic lettering. The differences help me focus on different parts of the invitation at the same time. The illustrations and colors keep me engaged in the invitation.
This poster illustrates how hierarchy plays a vital role in conveying a message to the audience. The title of the event is obviously the dominant element and then the information about the event becomes secondary by changing the typeface as well as the size. the logos of sponsors become the 3rd element that you notice by making them a lot smaller than the type.
