This is "The J. Paul Getty Museum Los Angeles" mug designed by the illustrious post-modern architect Richard Meier and depicts an abstract graphic image of Meier's building. I suspect, the mug is from 1997 when the Getty Museum opened though the art work seems late 80's to early 90's and reminds me of David Hockney's paintings.
Near mint condition.
