Many of those old Bristish luxury cars had similar lines... I do think I saw the flying lady on the grill...

http://www.swammelstein.nl/models.htm This site claims to have pics of all RR models....

PS.... for many years the only difference between a Bentley and a Rolls was that the sides of the grill on the Rolls were made convex to make them look flat to the human eye... whereas the Bentley grill was in fact flat on the side... but flat chrome looks concave to the human eye....and the charged about $200 difference for the Rolls as a result of the extra work...
