The one thing many travelers have in common is that most like to document where they've been, which is why the World Map Wall Decals would make the ideal decorative piece in the home.
Instead of painting or using wallpaper, put up the World Map Wall Decals. The wonderful wall decor is an overblown map in a silhouette form. What I love about this is that avid travelers can mark where they've been as a way of documenting their trips. Even if that's not what it's being used for, it can probably spark a conversation among guests or be an educational piece for the kids. It would be better if it included names of the cities from different countries, but this will do just as well.
