20th Anniversary Mug of the stamp made to Commemorate First Orbital Space Flight

This historical mug was created to recognize the 20th anniversary of the First Orbital Space Flight by John Glenn Jr. on February 20th, 1962. They did this by decorating the mug with the stamp made in remembrance of this moment forever marked in history. I included 2 screenshot images detailing everything to know about the making of that day and of the stamp to mark that day. Please read, it's very interesting. this mug is in excellent vintage condition with no chips or cracks.Measurements: 3.5" = Height 3" = Width
