I want to learn more about the following peice of art depicting backgammon:

Apparently some resourceful Romans also used the game to play a
classical version of strip poker. A painted glass exists that depicts
a young man and a girl seated in front of a backgammon board; they are
partially undressed, and nearby on the floor are pieces of clothing.
The inscription, "Devincavi", means "I think I've beaten you".

That appears in "The Backgammon Book" by Oswald Jacoby & John R. Crawford.
(The relevant chapter has even been put online here:

My question is only: What is that art work?  I presume the artist is
unknown, but I would like to know the title or other identifier and
where it is currently located.  Other details would be appreciated,
but aren't necessary.

The illustration appears on the back of a mirror:

There is some controversy about the identification of the game, however.
