"Vintage" can mean many different things; in most cases, it's a sort of boilerplate description for anything with an older aesthetic. This background doesn't quite fit that description.
It's contemporary thanks to its clever use of color and its bold font choice, and it grabs the viewer's attention by placing an intricate frame over its central text. However, it's also undeniably vintage--from the stately font to the small text under the main banner, it's a smart update on a classic style. This graphic uses a hip approach to set itself apart from the pack, and it's perfect as a sign, flyer or a web background.
