The Gateway To The North Mackinac Bridge Michigan's Upper Peninsula. You will love how nice these ceramic tiles shine! They are unique and affordable little gifts from Michigan's Upper Peninsula that everyone will love. Fine wall art comes in all sizes, and these are sized to fit any space! With so many to choose from, there is something for everyone! Images are hi-resolution with full cork backings. Note: sizes are measured by tile size so they will need a little extra room to hang as a triangle. Have fun choosing!
