Features artwork which is etched into the exterior surface of the front of this mug.
Etched on the front surface are images of the Wright Flyer and what I presume is one of the Wright Brothers. Above the airplane is etched "THE WRIGHT FLYER I" and beneath it is etched "DECEMBER 17, 1903"
On the back of this mug is etched "FIRST IN FLIGHT" with a paragraph below it describing the events of December 17, 1903.
Condition note: there is a small manufacturing error in the form of a depression in the rear upper surface. Please see the 4th photo where a red arrow is pointing to this.
