Wide Panel Cruet
I have very little information about these rare cruets. It's been suggested that it's Imperial, but I have no proof. This sold in 1994 for $75; another in 1999 for $525, and a third in 2002 for $45. On eBay in 2006, one with a different stopper brought $101.

In 2014 one with a stopper sold for $80.
