TRANSPORTATION & TRAVEL WALL ART: A placid sailboat drifting lazily on ocean currents. A bike (who doesn't love bicycles)? A vintage airplane. What do these have in common? Transportation. But more importantly movement. Going places. ''Getting somewhere.'' At a slow relaxing pace or at a fevered pitch. Moving. The reason people are attracted to transportation wall art is often because it gives them motivation to get moving. Or it can bring back wonderful memories of simpler times. It may reflect a hobby or collection. Whatever the reason, this art theme looks great on walls and sets a mood to your favorite rooms.
