Here is one of my all-time favorite things I have ever purchased from New York City and you can purchase these on Etsy as well.They are tumbled marble coasters with a print of a vintage map of New York City featured on the top. They look great in my living room, and are used every day.
You can find them on Etsy by going here or my clicking on the image: http://etsy.me/1hmxkJX
I also saw these awesome I Love New York coasters, which I think I might purchase for my dining room. I like the modern chic feel these coasters have. They are featured here: http://etsy.me/1hvuzoi
