When you find a vintage ashtray, there are two versions. One has no Fiesta mark on the bottom, instead, there are seven circles.
Later in production, the inner rings were discarded for the well-known ‘Genuine Fiesta HLCO’ stamp.
You can often find marks on the bottom of ashtrays, and the ashtrays have the distinction of being the only product in the Fiesta line that have broken circles, in this case, broken by the wells to hold cigarettes.
Medium green is, of course, the rarest.
