Writing in the December 2017 issue of the ICGA Carnival Pump, Don and Barb Chamberlain report that Don Leininger has a marigold version of the Imperial Paperweight. Apparently the only one known. They also report that in a document from Imperial's archives, the piece was known as a change tray.

I have found no reference to this item either in company documents or in catalogues of the company's production. However, a knowledge of the company's history and the judicious application of specific dates in that history, should allow us to establish a reasonable time frame and causation for the creation of this article.

It is important to know that the Imperial Paperweight carries all the known trademarks of the company, NUART and NUCUT were registered very early in the company's history; 1911 and 1914 respectively. The combination of the ironcross, or double I as called by some, in conjuction with the superimposed IM-PE-RI-al was not granted registration until 1921, the twentieth anniversary of it first glass production. I favor the latter date as being more significant and better fitting the time frame of events. Because of the obvious small quantity which were produced, we can soundly theorize that these pieces were probably made for a select group of employees or stockholders as a momento of this occasion.
The scenario would of course cast some doubt as to whether this item is a commenorative or a piece of advertising. I have elected to call it advertising in the event my scenario is all wet.
