Some landmarks in Chicago are recognizable to tourists and locals alike. Stock a selection so they remember their favorite destinations. Tiles come with a cork backing to prevent scratches on your table surfaces. Designs are printed using a process call dye sublimation. Inks are heat pressed onto the tile coating at high temperature where they turn into a gas and are absorbed into the tile. Light, heat and water will not affect the image because it is part of the tile instead of printed on top.
