"Design a series of four vintage travel posters, each representing a distinct historical period and location: A rustic scene in a 1500s European hamlet, an elegant 1750s Victorian ballroom, a lively 1900s New York City street with early automobiles, and a sleek, ultra-modern Tokyo skyline in 2024. Style each poster with period-appropriate art techniques and a slogan that invites the viewer to visit through time travel."
