The Central Park Map Travel Mug is a simple way to carry your hot or cold beverage, while walking around the Park. Etched with a 1909 Rand McNally map of Central Park, the leather sleeve is hand crafted from quality 5/6oz vegetable tanned leather. You can quickly switch between the travel lid for drinking, and the mason jar lid for transport. If you remove the metal ring and lid, the travel mug is microwave safe. The leather sleeve is removable for easy cleaning. Best of all, if you break your mug, the mason jar can be replaced at little cost.
