Printed on this mug is the sketch created by Bob Lazar during the filming of Jeremy Corbell's film, 'Bob Lazar, Area 51 and Flying Saucers'. In the movie, Bob was showing the component layout on the alien craft he worked on, nicknamed The Sport Model'. The cutaway view sketch shows the 3 gravity amplifiers & emitters that propel the craft and the heart shaped field that surrounds it while in operation.
